Abstract:

AbstractFor the solar sytem giant planets the measurement of the gravitational moments J2 and J4 provided valuable information about the interior structure. However, for extrasolar planets the gravitational moments are not accessible. Nevertheless, an additional constraint for extrasolar planets can be obtained from the tidal Love number k2, which, to first order, is equivalent to J2. k2 quantifies the quadrupolic gravity field deformation at the surface of the planet in response to an external perturbing body and depends solely on the planet's internal density distribution. On the other hand, the inverse deduction of the density distribution of the planet from k2 is non-unique. The Love number k2 is a potentially observable parameter that can be obtained from tidally induced apsidal precession of close-in planets (Ragozzine & Wolf 2009) or from the orbital parameters of specific two-planet systems in apsidal alignment (Mardling 2007). We find that for a given k2, a precise value for the core mass cannot be derived. However, a maximum core mass can be inferred which equals the core mass predicted by homogeneous zero metallicity envelope models. Using the example of the extrasolar transiting planet HAT-P-13b we show to what extend planetary models can be constrained by taking into account the tidal Love number k2.

Abstract:

Objective - This research aims to investigate the influence of the love of money and greed on the individual's ethical sensitivity. Methodology/Technique - The samples used are 50 students of accounting from Jember University. Path analysis is used to test the hypotheses. Findings - The results show that there is an influence of the Love of Money on Greed. Theoretically, when one has fulfilled one's primary needs, one is able to survive. But human beings are not easily satisfied thus, they would always want to gain more. A person who loves money would be glad when he/she owns money since the person thinks that money can give him/her the comforts of life and the money that he/she has, can be used in whatever way he/she prefers. Novelty - Unlike previous studies, this study looks at the topic from the Islamic perspective. Type of Paper Review Keywords: Accounting; Love of Money; Greed; Ethical Sensitivity; Indonesia. JEL Classification: I21, M41.

Abstract:

The tidal deformability of a self-gravitating object leaves an imprint on the gravitational-wave signal of an inspiral which is paramount to measure the internal structure of the binary components. We unveil here a surprisingly unnoticed effect: in the extreme mass-ratio limit the tidal Love number of the central object (i.e. the quadrupole moment induced by the tidal field of its companion) affects the gravitational waveform at the leading order in the mass ratio. This effect acts as a magnifying glass for the tidal deformability of supermassive objects but was so far neglected, probably because the tidal Love numbers of a black hole (the most natural candidate for a compact supermassive object) are identically zero. We argue that extreme mass-ratio inspirals detectable by the future laser interferometric space antenna (LISA) mission might place constraints on the tidal Love numbers of the central object which are roughly eight orders of magnitude more stringent than current ones on neutron stars, potentially probing all models of black hole mimickers proposed so far.

Abstract:

SUMMARY Isostasy explains why observed gravity anomalies are generally much weaker than what is expected from topography alone, and why planetary crusts can support high topography without breaking up. On Earth, it is used to subtract from gravity anomalies the contribution of nearly compensated surface topography. On icy moons and dwarf planets, it constrains the compensation depth which is identified with the thickness of the rigid layer above a soft layer or a global subsurface ocean. Classical isostasy, however, is not self-consistent, neglects internal stresses and geoid contributions to topographical support, and yields ambiguous predictions of geoid anomalies. Isostasy should instead be defined either by minimizing deviatoric elastic stresses within the silicate crust or icy shell, or by studying the dynamic response of the body in the long-time limit. In this paper, I implement the first option by formulating Airy isostatic equilibrium as the linear response of an elastic shell to a combination of surface and internal loads. Isostatic ratios are defined in terms of deviatoric Love numbers which quantify deviations with respect to a fluid state. The Love number approach separates the physics of isostasy from the technicalities of elastic-gravitational spherical deformations, and provides flexibility in the choice of the interior structure. Since elastic isostasy is invariant under a global rescaling of the shell shear modulus, it can be defined in the fluid shell limit, which is simpler and reveals the deep connection with the asymptotic state of dynamic isostasy. If the shell is homogeneous, minimum stress isostasy is dual to a variant of elastic isostasy called zero deflection isostasy, which is less physical but simpler to compute. Each isostatic model is combined with general boundary conditions applied at the surface and bottom of the shell, resulting in one-parameter isostatic families. At long wavelength, the thin shell limit is a good approximation, in which case the influence of boundary conditions disappears as all isostatic families members yield the same isostatic ratios. At short wavelength, topography is supported by shallow stresses so that Airy isostasy becomes similar to either pure top loading or pure bottom loading. The isostatic ratios of incompressible bodies with three homogeneous layers are given in analytical form in the text and in complementary software.

Abstract:

ABSTRACT The space-borne gravitational wave interferometer, Laser Interferometer Space Antenna, is expected to detect signals from numerous binary white dwarfs. At small orbital separation, rapid rotation and large tidal bulges may allow for the stellar internal structure to be probed through such observations. Finite-size effects are encoded in quantities like the moment of inertia (I), tidal Love number (Love), and quadrupole moment (Q). The universal relations among them (I–Love–Q relations) can be used to reduce the number of parameters in the gravitational-wave templates. We here study I–Love–Q relations for more realistic white dwarf models than used in previous studies. In particular, we extend previous works by including (i) differential rotation and (ii) internal temperature profiles taken from detailed stellar evolution calculations. We use the publicly available stellar evolution code mesa to generate cooling models of both low- and high-mass white dwarfs. We show that differential rotation causes the I–Q relation (and similarly the Love–Q relation) to deviate from that of constant rotation. We also find that the introduction of finite temperatures causes the white dwarf to move along the zero-temperature mass sequence of I–Q values, moving towards values that suggest a lower mass. We further find that after only a few Myr, high-mass white dwarfs are well described by the zero-temperature model, suggesting that the relations with zero temperature may be good enough in most practical cases. Low-mass, He-core white dwarfs with thick hydrogen envelopes may undergo long periods of H burning which sustain the stellar temperature and allow deviations from the I–Love–Q relations for longer times.

Abstract:

The present study aims at explicating the theme of love in the folk tale Heer Ranjha through the discourse stylistics perspective. To do this, Fairclough (2015) model is employed with a focus on lexical choices. The metaphors used in the dialogues portraying the theme of love have been carefully selected, and further the linguistic pattern employed has been significantly discussed to highlight the embedded theme of love as a dominant human emotion in folk tales. The study also aims at providing a richer, more complex and enlightened canvas of feminist theory highlighting the role of women and power relations between the two sexes. The data comprises on twenty passages from the translation of ‘Heer Ranjha’ by Usborne (1973) where the translator claims to have translated the epilogue at full length while the rest of the poem has been condensed without omitting anything significantly important to the theme. The study throws light on the language of the folk tale, which reflects socio-cultural features such as the patriarchic family structure of the time through the language choices. The flute, a bamboo musical instrument, is a metaphor of love in a dream-like romantic sound. Finally, this paper helps to develop a better understanding of folktales in a particular socio-cultural background.

Abstract:

AbstractAccurately understanding the interior structure of extra-solar planets is critical for inferring their formation and evolution and resolving the origin of anomalous planetary radii. The internal density distribution of the planet has a direct effect on the star-planet orbit through the gravitational quadrupole of rotational and tidal bulges, measured by the planetary Love number (k2p, twice the apsidal motion constant). We find that the quadrupole of the planetary tidal bulges dominates the rate of apsidal precession of single very hot Jupiters by more than an order of magnitude over general relativity and the stellar quadrupole. For the shortest-period planets, the planetary interior induces precession of a few degrees per year. By investigating the full photometric signal of apsidal precession, we find that transit timing induces a relatively small signal compared to the changes in transit shapes. With its long baseline of ultra-precise photometry, the future space-based Kepler mission should be able to realistically detect the presence or absence of a core in very hot Jupiters with orbital eccentricities as low as e ~ 0.001. We show that the signal due to k2p is not degenerate with other parameters and has a unique signature on the transit light curve. This technique, outlined in more detail in Ragozzine & Wolf 2008 provides the first readily employed method for directly probing the interiors of extra-solar planets.

Abstract:

This article reviews how corporate social responsibility, in particular its environmental practices, is being mobilised in practice by companies. We discuss that the current engagement with the Anthropocene is more a marketing argument supporting a capitalist discourse, rather than an ethical approach towards business. Thus, we call for a more sustainable approach in corporate social responsibility, not as a communication tool, but as a genuine response to Anthropocene conditions and shared stewardship, rather than a marketisation of corporate social responsibility. We suggest the establishment of an international corporate social responsibility certification entity that would advise companies in corporate social responsibility practices in the Anthropocene Earth.

Abstract:

Transit timing variations (TTVs) can be a very efficient way of constraining masses and eccentricities of multi-planet systems. Recent measurements of the TTVs of TRAPPIST-1 have led to an estimate of the masses of the planets, enabling an estimate of their densities and their water content. A recent TTV analysis using data obtained in the past two years yields a 34 and 13% increase in mass for TRAPPIST-1b and c, respectively. In most studies to date, a Newtonian N-body model is used to fit the masses of the planets, while sometimes general relativity is accounted for. Using the Posidonius N-body code, in this paper we show that in the case of the TRAPPIST-1 system, non-Newtonian effects might also be relevant to correctly model the dynamics of the system and the resulting TTVs. In particular, using standard values of the tidal Love number k2 (accounting for the tidal deformation) and the fluid Love number k2f (accounting for the rotational flattening) leads to differences in the TTVs of TRAPPIST-1b and c that are similar to the differences caused by general relativity. We also show that relaxing the values of tidal Love number k2 and the fluid Love number k2f can lead to TTVs which differ by as much as a few 10 s on a 3−4-yr timescale, which is a potentially observable level. The high values of the Love numbers needed to reach observable levels for the TTVs could be achieved for planets with a liquid ocean, which if detected might then be interpreted as a sign that TRAPPIST-1b and TRAPPIST-1c could have a liquid magma ocean. For TRAPPIST-1 and similar systems the models to fit the TTVs should potentially account for general relativity, for the tidal deformation of the planets, for the rotational deformation of the planets, and to a lesser extent for the rotational deformation of the star, which would add up to 7 × 2 + 1 = 15 additional free parameters in the case of TRAPPIST-1.

Abstract:

Space missions such as CoRoT and Kepler have made the transit method the most successful technique in observing extrasolar planets. However, although the mean density of a planet can be derived from its measured mass and radius, no details about its interior structure, such as the density profile, can be inferred so far. If determined precisely enough, the shape of the transiting light curve might, in principle, reveal the shape of the planet, and in particular, its deviation from spherical symmetry. These deformations are caused, for instance, by the tidal interactions of the planet with the host star and by other planets that might orbit in the planetary system. The deformations depend on the interior structure of the planet and its composition and can be parameterized as Love numbers kn. This means that the diversity of possible interior models for extrasolar planets might be confined by measuring this quantity. We present results of a wide-ranging parameter study in planet mass, surface temperature, and layer mass fractions on such models for super-Earths and their corresponding Love numbers. Based on these data, we find that k2 is most useful in assessing the ratio of rocky material to iron and in ruling out certain compositional configurations for measured mass and radius values, such as a prominent core consisting of rocky material. Furthermore, we apply the procedure to exoplanets K2-3b and c and predict that K2-3c probably has a thick outer water layer.

Abstract:

Context. Increasing our knowledge of the interior structure, composition, and density distribution of exoplanets is crucial to make progress in the understanding of exoplanetary formation, migration and habitability. However, the directly measurable mass and radius values offer little constraint on interior structure, because the inverse problem is highly degenerate. Therefore, there is a clear need for a third observable of exoplanet interiors. This third observable can be the k2 fluid Love number which measures the central mass concentration of an exoplanet. Aims. The aims of this paper are (i) to develop a basic model to fit the long-term radial velocity and TTV variations caused by tidal interactions, (ii) to apply the model to the WASP-18Ab system, and (iii) to estimate the Love number of the planet. Methods. Archival radial velocity, transit and occultation timing data were collected and fitted using the model introduced here. Results. The best model fit to the archival radial velocity and timing data of WASP-18Ab was obtained with a Love number of the massive (~10 MJup) hot Jupiter WASP-18Ab: k2,Love = 0.62−0.19+0.55. This causes apsidal motion in the system, at a rate of ~0.0087 ± 0.0033°∕days ≊ 31.3 ± 11.8 arcsec day−1. When checking possible causes of periastron precession, other than the relativistic term or the non-spherical shape of the components, we found a companion star to the WASP-18 system, named WASP-18B which is a probable M6.5V dwarf with ~0.1 M⊙ at 3519 AU distance from the transit host star. We also find that small orbital eccentricities may be real, rather than an apparent effect caused by the non-spherical stellar shape.

Abstract:

Context.The mass and radius of a planet directly provide its bulk density, which can be interpreted in terms of its overall composition. Any measure of the radial mass distribution provides a first step in constraining the interior structure. The fluid Love numberk2provides such a measure, and estimates ofk2for extrasolar planets are expected to be available in the coming years thanks to improved observational facilities and the ever-extending temporal baseline of extrasolar planet observations.Aims.We derive a method for calculating the Love numbersknof any object given its density profile, which is routinely calculated from interior structure codes.Methods.We used the matrix-propagator technique, a method frequently used in the geophysical community.Results.We detail the calculation and apply it to the case of GJ 436b, a classical example of the degeneracy of mass-radius relationships, to illustrate how measurements ofk2can improve our understanding of the interior structure of extrasolar planets. We implemented the method in a code that is fast, freely available, and easy to combine with preexisting interior structure codes. While the linear approach presented here for the calculation of the Love numbers cannot treat the presence of nonlinear effects that may arise under certain dynamical conditions, it is applicable to close-in gaseous extrasolar planets like hot Jupiters, likely the first targets for whichk2will be measured.

Abstract:

The concept of planetary health blurs the artificial lines between health at scales of person, place and planet. At the same time, it emphasizes the integration of biological, psychological, social and cultural aspects of health in the modern environment. Our grandest challenges in the Anthropocene ultimately stem from human attitudes to each other and to our environment. However, solutions rarely confront the underlying value systems that created these interconnected problems, or the attitudes that perpetuate them. Too often, the dominant focus is on the “worst of human nature”, and devalues or neglects the importance of empathy, kindness, hope, love, creativity and mutual respect—the deeper values that unite, empower and refocus priorities of individuals and groups. Here, we call to normalize more creative, mutualistic approaches—including the perspectives of traditional and indigenous cultures—to positively influence normative value systems. We revisit the power of inspiration with the profound example of the Apollo 8 Earthrise photo which galvanized a fledgling planetary health movement over 50 years ago. Through the inaugural Earth Day that followed, we are reminded that its early organizers were not constrained in how they defined the “environment”. They and their primary speakers were as concerned about value systems as they were about pollution—that we cannot hope to solve our problems without addressing the attitudes that created them in the first place. We explore the ways in which the awe of Earthrise—and the contemporary science of creativity and studies of utopian thinking—might reinvigorate imagination, kindness and mutualism. We revisit the fundamental challenge offered by Pulitzer-Prize-winning microbiologist Rene Dubos and others in the afterglow of the Earthrise photo, and the inaugural Earth Day. This is a question of imagination: What kind of world we want to live in?

Abstract:

SUMMARY Planetary-scale mass redistributions occur on Earth for certain spatiotemporal periods, and these surface mass changes excite the global periodic loading deformations of a viscoelastic Earth. However, the characteristics of periodic viscoelastic deformations have not been well investigated even in a simple earth model. In this study, we derive the semi-analytical Green's functions (fully analytical Love numbers) for long-standing point sources with given periods using a modified asymptotic scheme in a homogeneous Maxwell spherical earth model. Here, the asymptotic scheme is needed in order to obtain accurate semi-analytical time-dependent Green's functions. The amplitudes and phases of the Green's functions may be biased if only the series summations of the Love numbers are used because the influence of viscoelasticity is degree-dependent. We compare the viscoelastic and elastic periodic Green's functions with different material viscosities and loading periods and investigate the amplitude increase percentage and phase delay of the periodic displacement and geoid change. For example, our analysis revealed that the viscosity increases the amplitude by 40–120 per cent and delays the phase approximately −100° to 60° for the displacement and geoid change when bearing a 10-yr loading period, assuming a viscosity of 1018 Pa s and a shear modulus 4 × 1010 Pa.

Abstract:

This text examines the effects of climate change on cultural ideas regarding the colonization of space. More specifically, this paper explores the ways which the looming danger of climate catastrophe has fueled the growth of post-planetary culture: a culture that dreams of a human destiny beyond the Earth. It takes as its object both science fiction texts and non-fiction futurological pronouncements by scientists and entrepreneurs. What emerges from this study is the observation that unlike climate skeptics, post-planetarists believe that climate change is real. Yet like climate skeptics, they subordinate climate action to other priorities, putting the construction of a means of escaping this planet above climate action. But why do these post-planetarists wish to fly? Via a close reading of David Brin’s Earth, we argue that one of the key characteristics of post-planetary culture is a feeling of hatred and alienation towards the Earth. This hatred is both re-enforced by the ravages of climate change even as it contributes to this destruction by blocking post-planetarists from whole-heartedly engaging in climate action. In order to illustrate an antidote to this pathological cultural reaction to our current crisis, I present a close reading Kim Stanley Robinson’s Aurora, exploring how this text is both a critique of post-planetarism and a guide to renewing our love for the Earth.

Abstract:

Context. The Love number h2 describes the radial tidal displacements of Mercury’s surface and allows constraints to be set on the inner core size when combined with the potential Love number k2. Knowledge of Mercury’s inner core size is fundamental to gaining insights into the planet’s thermal evolution and dynamo working principle. The BepiColombo Laser Altimeter (BELA) is currently cruising to Mercury as part of the BepiColombo mission and once it is in orbit around Mercury, it will acquire precise measurements of the planet’s surface topography, potentially including variability that is due to tidal deformation. Aims. We use synthetic measurements acquired using BELA to assess how accurately Mercury’s tidal Love number h2 can be determined by laser altimetry. Methods. We generated realistic, synthetic BELA measurements, including instrument performance, orbit determination, as well as uncertainties in spacecraft attitude and Mercury’s libration. We then retrieved Mercury’s h2 and global topography from the synthetic data through a joint inversion. Results. Our results suggest that h2 can be determined with an absolute accuracy of ± 0.012, enabling a determination of Mercury’s inner core size to ± 150 km given the inner core is sufficiently large (>800 km). We also show that the uncertainty of h2 depends strongly on the assumed scaling behavior of the topography at small scales and on the periodic misalignment of the instrument.

Abstract:

Loyalty and reliability have always been the aim of high ranked societies, striving for better living. Loyalty and reliability are like a flower that blooms out of pleasant and friendly atmosphere, found online people with similar mind-sets, wanting to achieve prosperous goals. Envy, hatred and jealousy don’t give loyalty a chance to flourish instead, they remove it immediately. This passion only grows and propagates in the atmosphere of love, kindness and great heartedness, while it withers away and ends slowly in the hostile environment. Every citizen in Pakistan is a servant and well-wisher of Pakistan. The loyalty of Muslim community is appreciable at its place, but non-Muslim citizens are also heading forward in serving Pakistan. It is only through this unity that the conditions of stress and misconceptions can be eliminated among one another. In this article, in the historical context of Pakistan, it is sought to clarify that non-Muslims of Pakistan, like the Muslim citizens of Pakistan, are loyal and faithful to Pakistan and love the soil of their homeland, so that their haters get involved in the color of love, and the fortunes of mutual misunderstandings can be eliminated and the honorable citizens of Pakistan can promote peace and prosperity for Pakistan.
