SUMMARY:Habitability of terrestrial planets: study with 1D and 3D climate 
 models - Guillaume Chaverot

DESCRIPTION:In the study of small terrestrial planets\, the runaway greenh
 ouse is of great importance by separating two drastically different popula
 tions: temperate habitable planets and hot water-rich uninhabitable planet
 s. It also delimits the inner edge of the habitable zone\, that is a simpl
 e but powerful tool to study large samples of targets. It is one of the ke
 y processes that we need to understand preparing the future missions that 
 aim to detect and characterize small terrestrial planets (e.g. PLATO\, Lif
 e\, HWO).\n\nIn this presentation\, we will discuss the limits of habitabi
 lity using climate modeling (1D and 3D) to try to build a comprehensive ov
 erview of the intrinsic complexity of this topic. We will see the implicat
 ions of the runaway greenhouse\, but also how the different 3D processes h
 appening in the atmosphere could induce various climates for this type of 
 planet\, through climate multistability for instance.
