Texto completoIn this thesis I present the work I performed during the initial construction and deployment of the second telescope in the KELT project and I report the results of the search for transiting exoplanets and variable stars using one of the first commissioning datasets obtained with the telescope. The KELT-South telescope is located in Sutherland, South Africa and construction started in 2008. The telescope has been operating at full capacity since 2010, after two commissioning seasons from late 2008 to early 2010. I developed all the code that allows it to be fully automatic and robotic and over the last 5 years I have been responsible for the observing operations and general maintenance of the telescope. I also developed many other software tools that help with the identification of the exoplanet candidates. The Kilodegree Extremely Little Telescope (KELT) project at present consists of two robotic, wide field, small aperture telescopes that are designed primarily to find transiting exoplanets around bright stars in the magnitude range 8 < V < 11. Transiting planets orbiting bright stars can be studied with intense follow-up programs with relative ease on larger telescopes, making them favourable targets to determine the atmospheric composition of the planet as well as a host of other properties that cannot be obtained from planets orbiting fainter stars. Of the known 1811 (August 2014) exoplanets only 60 are transiting stars with V < 11 and only 16 of those have been found from the southern hemisphere. The discovery of more of these exoplanets will help constrain the theories of formation and evolution of short period, gas giant exoplanets. Data reduction on one of the commissioning datasets was completed in 2012. The dataset spans 46 days and lightcurves for 78297 objects were obtained. I performed a search for periodicities in the lightcurves and found that 1411 stars showed clear signs of variability and these objects were compiled into a catalogue of possible variable stars. 1018 of the catalogue members were not previously known to be variable. I searched for planetary transits and eight possible exoplanet candidates were identified. Photometric follow-up observations of two targets eliminated them as exoplanet candidates, each being a blended eclipsing binary system. The remaining six candidates are awaiting follow-up observations at present. Although the commissioning dataset served primarily to refine the data reduction pipeline and the procedures I used to find variable stars, I have demonstrated that the KELT-South telescope is capable of detecting the kinds of signals required for exoplanet discovery.

Texto completoResumo: Esta tese de doutorado traz uma abordagem experimental sobre mecanismos de geração, desenvolvimento e propagação em canal de instabilidade na superfície livre de um escoamento de fluido não-Newtoniano. Estas instabilidades, quando evoluem para um padrão estável, exibem comprimento, amplitude e celeridade bem definidos, sendo denominadas roll waves. Na literatura existe uma lacuna no que diz respeito às medições destes fenômenos em condições controladas de laboratório, e com pouquíssimos registros, quando presentes em eventos naturais. Assim, buscou-se neste trabalho projetar e implementar um aparato experimental operacional e de baixo custo com o objetivo de gerar e aferir tais instabilidades, sob condições controladas e sem a influência de vibrações externas (canalete posicionado sobre uma mesa inercial), seguindo metodologia de ensaio proposta e testada. O fluido teste utilizado foi o gel de carbopol 996, que apresentou boa estabilidade e propriedades reológicas aderentes ao modelo de Herschel-Bulkley, tal qual as lamas encontradas em pés de barragens, lamas oriundas de fluxos hiperconcentrados ou de corridas propriamente ditas. Um sistema de sucção-recalque, através de uma bomba hidráulica de cavidade progressiva, impulsionava o gel para o canal de ensaio, garantindo fluxo contínuo do material em regime de recirculação. Para gerar as instabilidades na superfície livre, foi imposta, a montante do canal, uma perturbação, por meio de um pulso de ar controlado em intensidade e...

Texto completoAsteroids are involved in understanding several key issues in Solar System science and the space environment of our planet, such as the conditions of the Solar System during its formation, the delivery of water and organic molecules to Earth, the potential danger of NEA and their role in affecting Earth's climate.Stellar occultation events are a unique opportunity to obtain from the ground very accurate asteroid astrometry, close to the performance of Gaia, and shapes/sizes. When an asteroid hides the light of a star, the uncertainty of its instantaneous position can be similar to that of the target star. By exploiting the accuracy of Gaia DR2 on both asteroids and stars, stellar occultation prediction and exploitation becomes an effective method to systematically collect asteroid astrometry.The improvement of predictions through Gaia DR2 is proven via statistics of real predictions and comparison between stellar occultation predictions with Gaia DR2 for asteroids and other, such as Astorb and MPCORB, to verify which fit better to observed chords of past occultations.At the same time, asteroid occultations can offer the possibility to confirm or discover double stars, in a range of small angular separations very complementary to the resolution accessible to Gaia itself. We will present statistics and simulations showing the improvement expected in the prediction of asteroid occultations thanks to Gaia astrometry, in particular regarding the smaller uncertainties on the proper motion of target stars.Through a bayesian approach, the Bayesian Inference Method (BIM), we determine in the parameter space (duration; centre epoch; flux drop; star brightness) the domain of detectable events from a single site. Our study prepares the exploitation of the 0.5-m robotic telescope at "Plateau de Calern" (Southern France) UniversCity, for which we determine the range of asteroid size and star brightness that we expect to reach. This facility will start operations after this work is over. The results obtained regarding the performance were compared with the previously used method to deriving all the relevant parameters (Least Squares Fit), with false positive signals to determine when these are most likely, and with several real observations, to verify the viability of this new method.After this work simulating the expected performance of UniversCity with the available equipment, the plan is to apply these limitations to predicted events and maximize the efficiency of the telescope's use. For that end, and accounting for all these factors, a survey was made to estimate how many events would be observable with a robotic telescope in a 1-year period with the current star and asteroid catalogues. To account for improvements in the asteroid uncertainties thanks to Gaia, for each event we checked what the impact on the likelihood would be if the asteroid had an uncertainty 2, 5, 10 or 20 times smaller, and results for each regime were compiled.We also analyzed the data of the 14 099 asteroids present DR2, how this impacted the semi-major axis (a) uncertainty, and how that would translate into improvements on stellar occultation predictions. This was made for two different weighting schemes, the one used for AstDyS (Farnocchia et al.) and one developed by the team, using observation residuals and occultations from the past to verify that the new weighting scheme would bring an improvement.Thanks to the collaboration with several astronomers, 16 observations were made throughout this work, with the three positives being analyzed with the new bayesian approach, which was also used for a few other observations where the photometric data was shared

Texto completoDespite having strong theoretical models, the current limitation in our understanding of the small-scale structures of galaxies is linked to the lack of observational evidences. Many powerful telescopes and instruments have been developed in the last decades, however one of these strongest tools, namely Adaptive Optics (AO), can only be used on a very limited number of targets. Indeed, for AO to be efficient, a bright star is required close to the scientific target, typically under 30 . This is mandatory for the AO systems to be able to measure the atmospheric turbulence and this condition is rarely satisfied for extended extragalactic targets such as galaxies. The main part of this thesis work consisted in going deeper in the analysis of the inner tens of parsecs of Active Nuclei (AGN) by combining different techniques to obtain and to interpret new data. In this context, we developed a new radiative transfer code to analyse the polarimetric data. A second part of my work was dedicated to a high angular resolution study of Super Star Clusters (SSC) in a new system, thanks to data obtained with the AO demonstrator CANARY instrument

Texto completoTridimensional reconstruction method has become essential for applications suchas the characterization and analysis of surfaces. In this thesis, aims are to increase the qualityof 3d reconstructions by photometric stereo. This method is based on two principles, reversinglight-matter interaction model and configuration of a lighting system. With diffuse surfaces,the photometric stereo use three captured images from a fixed point of view for differentillumination directions. Its main advantage is to extract the color and geometric propertiesfor the textured rough surfaces. However, its application requires to make assumptions thatare not credible in real cases. This problem generates significant errors in the reconstructions.To reduce them, we offer various solutions around the overall consideration of the acquisitionchain. Our contribution focuses on the characterization and modeling of the lighting system,the acquisition sensor and improved image quality. We are also interested to optimize acquisitionprotocol in the case of specular surface or shading due to the surface geometry. Ourresults show that the inclusion of these features in the inversion of a BRDF model allowsan improvement of 3d reconstructions as well as the possibility of reducing the size of theacquisition systems
