Primitive asteroids in the Main Belt possess one of the most pristine inventories of materials in the Solar System. Main Belt primitive asteroids are particularly interesting due to clear evidence of phyllosilicates, i.e., silicates that have encountered liquid water and undergone chemical alteration. Since asteroids are thought to be likely

To warn about potential asteroid or comet impacts, we must first observe and discover these objects through dedicated NEO surveys. Most current and planned surveys are ground-based and use visible light, but they face limitations like weather dependency, limited sky visibility, difficulty detecting at low galactic latitudes, and inability to

Interaction phenomena between atmospheric layers in planetary atmospheres give rise to highly complex exchanges influencing thermal structure, composition and dynamics. In particular, the question of hydrodynamic escape in exoplanet atmospheres is a key issue for quantifying the mass loss in these atmospheres. Short-period exoplanets subject to
