Propriétés de surface et structure interne des objets Trans-Neptuniens et des Centaures : un nouveau modèle d'évolution thermique 3D by Aurélie Guilbert-Lepoutre ( Book )

Small Icy bodies of the Solar System are mainly constituted by Transneptunian Objects and Centaurs. These two populations are composed of numerous bodies, whose dynamical, physical and chemical properties can be very different. Their observations have remained challenging until recently. Thus, the study of the Transneptunian région is a research field in rapid and constant evolution. TNOs and Centaurs should be composed of varions ices. At the very beginning of this thesis, an ESO Large Program has been undertaken, in order to constrain thé surface composition of a significant sample of bodies. I was in charge of the H+K spectra obtained with the new instrument SINFONI. I therefore had to establish an optimized observation technique and a performant data reduction procedure, for which each step has been widely tested. Each spectrum has been analyzed individually, and a radiative transfer model has been applied to determine the surface composition of each object. Absorption bands attributed to water ice and other volatil ices have been detected. The presence of some volatil ices on these objects' surfaces raises questions about the possible internal activity they can undergo. I consequently developed a three-dimensional thermal model, using a mathematical solution limiting the computation time. This new internal evolution model allows to compute lateral beat fluxes and 3D boundary conditions, without any excessive computation time. I tested the influence of the most critical parameters such as the formation time of the objects, the matrix thermal conductivity, etc. The main results throw new leads for the observations interpretation. Finally, I managed to draw a portrait of Centaur 10199 Chariklo: the data obtained in the framework of the Large Program show indeed important variations compared to the previously published ones. Several hypothesis are considered to explain these changes: spatial variations, temporal variations, or cometary outbursts. Observational data alone do not allow to discard any of those three explanations. I therefore applied the 3D thermal model which allows to exclude some temporal variations
