| الوصف: | The minor bodies of the Solar System are the remnants of the primordial planetesimal population, their investigation can hence improve our knowledge about the environment conditions in the solar nebula, and the thermal and physical processes that took place in the early phases of the Solar System. During my Phd, I focused on the physical characterization of the asteroids (2867) Steins and (21) Lutetia, targets of the Esa-Rosetta space mission, and of the minor bodies of the outer Solar System (Centaurs et Trans-Neptunian Objects, TNOS). I performed visible photometric and spectroscopic observations of Steins and Lutetia using the Telescopio Nazionale Galileo, from the reduction, and the analysis, and the interpretation of the obtained data, I improved the physical knowledge of both the objects prior to the Rosetta fly-by. In this thesis I also present the results I obtained as part of large programme performed at the European Southern Observatory on Centaurs and the Trans-Neptunian Objects. I contributed to the interpretation of the obtained spectra using radiative transfer models. On the basis of the obtained photometric colors, I derived the taxonomic classification of the observed objects, and I performed a statistical analysis using also the whole available literature looking for correlations between taxonomy and dynamics. From the interpretation of the light curves I gathered information about the rotation, shape and density of the objects under analysis, and I investigated the density statistics of the small bodies of the outer Solar System combining these new results with literature data. ; Les petits corps du système solaire sont les vestiges des planétésimaux du disque primordial. Leur étude peut améliorer notre connaissance des conditions présentes dans la nébuleuse solaire, et des processus thermiques et physiques qui ont eu lieu pendant les premières phases de vie du système solaire. Pendant mon doctorat, je me suis concentré sur la caractérisation physique des astéroïdes (2867) Steins et (21) ... |
