Mars-Solar wind interaction: coupling between hybrid and exospheric models

Résumé

Solar wind interacts efficiently with Mars, it contributes to the erosion of the gazeous envelope and concurs to the atmospheric dynamic. The electromagnetic coupling with the neutral environment takes place with ionization processes which act as a catalyzer. A three-dimensional model has been developped to describe the solar wind and planetary plasma dynamic. Parallelization of the model has been accomplished and enable us to reach a grid resolution of 80 km or less, which are slightly more than plasma scale height in the ionophere. This model has been coupled to a three dimensional exospheric model giving the description of the neutral corona at different seasons. The seasonal effect of the thermosphere-exosphere on the Martian plasma environment is investigated and discussed in this presentation.
