Texto completoNear the magnetic poles, the magnetic field lines converge and form funnels called polar cusps. These very localized regions are very sensitive to interplanetary conditions. With its four satellites in, the CLUSTER mission allows for the first time the study of the tri-dimensional structure of boundary regions and the separation of spatial and temporal effects. We have exploited this capability to analyse the space and time dynamics of particle structures observed in the high-altitude polar cusp during events of reconnection between the terrestrial and interplanetary magnetic fields. Ionospheric observations at the footprint of polar cusps by the radar ESR show that polar cusp particles collide with the ionosphere and create ionization, heating. We have interpreted these observations from the modeling of their immediate and long-term effects on the ionospheric parameters

Texto completoPolycyclic Aromatic Hydrocarbons (PAHs) are now recognized as an important constituent of the interstellar medium gaseous phase. This family of molecules and in particular their ionic derivatives seems to be one of the most promising candidates for identification of the Diffuse Interstellar Bands (DIBs). These absorption bands are observed in the visible spectral range in the spectra of stars partially masked by gas cloud. The possible identification of PAHs as molecules responsible for these bands must be done through direct comparison with PAHs spectra recorded in conditions as close as possible to those of the interstellar medium. These low temperature and collision-free conditions can be recreated in the laboratory with supersonic beams. A van der Waals complex PAH-Ar is then ionized by resonant two-photon ionization. The ion absorption of a tunable visible laser photon causes the argon departure, and the detection of this dissociation by a mass spectrometer allows the recording of the PAH cation spectrum. Using this technique, the spectra of phenylacetylene(+)-Ar and of acenaphthene(+)-Ar could be obtained. The spectral profile is wide and lorentzian, showing an intramolecular dynamics dominated by ultrafast internal conversion. Two observation campaigns with the Télescope Bernard Lyot at the Pic du Midi allowed us to perform a systematic search for this broad bands, thanks to specific observational protocole and data processing. Upper-limits of abundance were determined for five PAH cations. Interstellar absorption zones identified in our spectra are of variable width and some of them are very likely the result of a combination due to several species. According to our measurements between 525 and 840 nm, the diffuse interstellar absorption represents 87 % of the interstellar absorption in front of BD +404220 star

Texto completoThis thesis presents a method to model air temperature differences within a conurbation . It relies on the analysis of the existing relationships between urban microclimate,geographical context and weather conditions. To do so, five air temperature networks located in three western France conurbations are utilized : Nantes, Angers and La Roche sur-Yon. A state of the art of the methods used to analyze urban climate is realized in chapter 1. In Chapter 2, air temperature networks are presented and analyzed and a methodology to correct biased data is proposed. In Chapter3 air temperature differences observed between the network sites are modelled from multiple linear regressions, using weather variables such as wind speed or solar radiation as explicative variables. Before the calibration step, data is sorted in a variety of ways in order to elaborate several models. The most performant model is identified in chapter4, confronting data observed using the five temperature networks to data estimated from each of the models.Chapter 5 illustrates the results of the work through three practical applications

Texto completoAprès avoir étudié l'effet des champs magnétiques extragalactiques sur la propagation des rayons cosmiques et l'influence sur le spectre, une grande partie du chapitre consacré à la description de l'expérience Auger sera laissée au système d'acquisition des données.
L'étude des gerbes atmosphériques initiées dans la haute atmosphère sous incidence rasante est riche d'enseignements concernant la possibilité de détection de neutrinos. Une procédure de reconstruction de l'énergie des gerbes rasantes hadroniques est formalisée et appliquée aux événements du prototype dans le chapitre 4, et le calcul de la sensibilité aux neutrinos du détecteur complet est donné dans le chapitre 5.
Enfin, l'analyse des données de l'année 2002 du réseau prototype de l'expérience Auger est l'objet du chapitre 6.

The stable pulsar PSR B1509-58 has been monitored with the Rossi X-ray Timing Explorer (RXTE) for seven years, since the start of that mission in January 1996. The long-term observation has enabled us to determine the first and the se cond period derivatives which can help us to search for other possible periodicities with data over a long time span. These possible periods may reveal properties of MHD waves on the surface of neutron stars, and thus promote our understand ing of neutron star physics. As the first of such attempts, we applied the H-test to RXTE/PCA data of PSR B1509-58 spanning from 1996 to 2002, consisting of more than 3*10^7 photon events, to search for periods other than the spin period. A search in the period range of 0~0.3 sec with 1-msec steps was conducted. No other periods were found. Some suspicious signatures, however, deserve further investigation. Moreover, the search sampling rate (1 msec per step) is too loose. A study with a higher sampling rate and a wider search range, which requires more computing time, is in preparation.
