The Theory and Simulation of Solar System Plasmas (TSSSP) group is busy with theoretical investigations of fundamental key physical processes in the solar system plasma, especially magnetic reconnection , as well as with their numerical simulation. For this sake mathematical models are being developed, appropriate particle and plasma simulations are carried out. The main emphasis of the research work in the group is put on the release of magnetic energy in the Universe and on the resulting turbulence, structure formation, plasma heating and particle acceleration to high energies. Examples are the phenomenon of magnetic storms and substorms, the heating of the solar corona as well as coronal mass ejections, the consequences of of solar plasma- and particle streams on the Earth ("space weather"). The theoretical investigations are carried out in close relation with the observational programs of the institute. From the heliospherc plasma processes conclusions are drawn also galactic and extragalactic plasma processes.

Meetings

Together with Dr. Gerard Belmont, Velizy, Jörg Büchner organizes regular meetings about the progress in theory and simulation of solar system plasmas in the course of the annual EGS- general assemblies in April each year since 1998. In 1998 the VII. Internationale Tagung on Plasma-Astrophysics and Space Physics was held in Lindau. The contents of the resulting proceedings ca be obtained by
