[MIS07-P20] Habitable zone for a planet with a small amount of water on its surface
Keywords:Exoplanet, Habitable Planet, Climate
We call a planet with a small amount of water on its surface, a land planet. Land planets have less water amount in its atmosphere and can radiate stronger planetary radiation than that for aqua planets, which have a large amount of water on its surface. Thus, a planet with a small amount of water on its surface has a wider habitable zone than that for a planet with a large amount of water on its surface [Abe et al., 2011; Kodama et al., 2018; 2019]. Here, we investigate the relationship between the width of the habitable zone and the surface water distribution using 3D GCM(General Circulation Model). We confirm that the habitable zone strongly depends on the surface environment. In this presentation, we summarize the climates and habitability for exo-land planets.
