| Abstract |
Kopparapu et al (2013) presented a new estimate on width of habitable zones. Habitable zone is defined as the circumstellar region in which life-supporting planets can exist. Kopparapu et al updated the radiation scheme used by Kasting (1993), and obtained new estimates of inner and outer edge of habitable zones. The inner edge of habitable zone is determined by runaway greenhouse limit and water loss limit. The outer edge of habitable zone is decided by a condition that surface temperature exceeds 273K for CO2 atmosphere. In presentation, I review Kopparapu et al (2013), and would like to discuss with participants about the results of Kopparapu et al. |
