| Outline of Final Research Achievements |
In order to estimate how habitable zone spreads in outer space and discuss about habitability for exoplanets including Super-Earths, a radiative transfer model was developed. The model is based on line-by-line method and calculates planetary radiative transfer from arbitrary temperature and mixing ratio profiles. A model based on k-distribution method was also developed for radiative-convective models and atmospheric global circulation models. These models indicate that there are two regimes for tropopause in planetary atmospheres, which is important for determining an inner edge of habitable zone. The tropopause regimes are a dry low-temperature regime and a moist high-temperature regime.
