H09: Plasma interactions with solar system bodies (1)

Friday, August 22  08:00-09:20,  Room #11

Session Chairs: Yoshiya Kasahara, Christian Mazelle

Plasma interactions with solar system bodies drastically change depending on the environment of the bodies such as presence of intrinsic magnetic field, atmosphere, and solid surface. For instance, the solar wind plasma directly impacts on the exosphere, atmosphere or surface of non-magnetized bodies such as Mars, Venus and moon and plasma wake is created in the nightside tail region, while magnetized planets are protected by their intrinsic magnetic fields and the solar wind-magnetosphere coupling plays an important role in plasma dynamics. As signatures of the interaction, various kinds of radio emissions and plasma waves are generated in numerous regions of our solar system. The aim of this session is to present recent progress in spacecraft observations, computer simulations and theoretical studies on plasma physics related to the solar wind and plasma flow interaction with solar system bodies. Papers related to future missions and research projects are also welcome.
