Description
Interaction between the solar wind and upper atmosphere facilitates various atmospheric escape processes from terrestrial planets. The escape rate depends on various conditions such as the distance from the Sun, solar activities, planetary size, atmospheric composition, and intrinsic magnetic field. The atmosphere retention is one of necessary conditions for habitable terrestrial exoplanets. In this invited talk, recent global MHD simulation studies of ion escape from unmagnetized and weakly magnetized planets will be reported with a focus on effects of the planetary intrinsic magnetic field.
