| Session Description | Different frontiers (internal/external) form through which intricate exchanges of energy and momenta take place, as the solar wind interacts with the environment of a planet. These frontiers may have different spatial features and time-dynamics according to the magnetized/unmagnetized environment of the planet. These exchanges develop over different spatial and temporal scales via different processes.Numerous approaches are commonly proposed in order to analyze the solar wind-magnetosphere interactions, and the subsequent energy partition taking place through different scales interactions Many works are based on numerical models using global multidimensional 2D/3D magnetohydrodynamic (MHD), Hybrid , Particle -in cell (PIC) and test particles simulations. The main difficulty is to identify (i) the dominant processes taking place through the frontiers and within the key regions of the magnetosphere, (ii) the scales over which main processes take place, (iii) whether the key regions are appropriately recovered in the different simulations and (iv) how the global energy partition is affected by any change of the solar wind conditions and/or of the interplanetary magnetic field. The purpose of this session is to put together and to compare results issued from different numerical simulation and theoretical approaches, in order to define their respective advantages and limitations. Reaching such a goal will also be supported by comparing with experimental results. Contributions obtained from experimental, numerical simulation and theoretical results for terrestrial and planetary magnetospheres are very welcome in the session. |
