H06: Boundary layers in terrestrial and planetary environments: Macro/micro-scale kinetic processes (1)

Thursday, August 21  08:00-09:20,  Room #11

Session Chairs: Bertrand Lembège, Gurbax Lakhina, Iku Shinohara

Natural boundary layers play a key role in the energy and momentum transfert between the solar wind and the planetary magnetosphere and/or between different regions within the magnetosphete itself. But, such layers are the sites of intricated microscopic/macroscopic processes which develop over micro/meso/macro-scales. These are based on various wave-particle interactions, nonlinear effects and nonstationary mechanisms, which partially or fully control the overall dynamics of these frontiers. The present session welcomes the discussion of results issued from theory, mono/multi-dimensional numerical simulations and experimental data obtained from various space missions. The comparison between these approaches is possible thanks to refined measurements obtained on board of recent multi-spacecraft missions (e.g., Cluster, Themis). Comparison with data issued from other missions (Geotail, Wind, Double Star,…) are also encouraged. Applications include magnetospheric, ionospheric and space plasma physics. Examples of boundary layers include: (i) collisionless shocks, (ii) the magnetopause, (iii) plasma sheet currents, (iv) magnetotail dynamics (including substorms), (v) plasmapause, (vi) potential drops in the ionosphere and cusp dynamics, (vii) basic particle acceleration processes, and (viii) dynamics of interfaces in active space experiments. Any contributions related to these topics are very welcome. Comparative analysis of results dedicated to terrestrial and planetary environments are also strongly encouraged, in order to approach a more synthetic view of their understanding.
