[MIS07-05] Climate of habitable exoplanets
★Invited Papers
Keywords:Exoplanets, Habitable planets, Climate
A large number of exoplanets have been detected since 1995. Some of these are expected to be rocky planets with Earth-like bulk composition and would have habitable climates. Habitable exoplanets are significant targets for observation of exo-terrestrial planets and exo-life.
Liquid water evaporates entirely when planets receive insolation above a certain critical value called the runaway greenhouse threshold. If planets receive very weak insolation, on the other hand, such planets lapse into the snowball state where the insolation is called the complete freezing threshold. Most of the studies for the habitable exo-terrestrial planets have discussed introducing the habitable zone, in which planets can maintain liquid water on their surface for the long term. Recently, the climate for exoplanets in the habitable zone has been estimated with three-dimensional general circulation models (3D GCMs).
In this presentation, I will review terrestrial exoplanets' habitability and climate and summarize future tasks and missions.
