| Zusammenfassung |
| The solar wind plasma interaction with the Martian exosphere is investigated
by means of 3-D multi-species hybrid simulations. The influence
of the solar EUV flux on the bow shock and the magnetic pile-up boundary is
examined by comparing two simulations describing the two extreme states of
the solar cycle. The hybrid formalism allows a kinetic description of each
ions species and a fluid description of electrons. The ionization processes
(photoionization, electron impact and charge exchange) are included
self-consistently in the model where the production rate is computed locally,
separately for each ionization act and for each neutral species. The results
of simulations are in a reasonable agreement with the observations made by
Phobos 2 and Mars Global Surveyor spacecraft. The position of the bow shock
and the magnetic pile-up boundary is weakly dependent of the solar EUV flux.
The motional electric field creates strong asymmetries for the two plasma
boundaries. |
