| Zusammenfassung |
| In June 2006 Venus Express crossed several times the outer boundary of the Venus induced
magnetosphere, its magnetosheath and the bow shock. During the same interval Cluster
spacecraft surveyed the dawn flank of the terrestrial magnetosphere, intersected the Earth’s
magnetopause and spent long time intervals in the magnetosheath. This configuration
offers the opportunity to investigate simultaneously the interface between Venus and
Earth’s outer plasma layers and the shocked solar wind. We discuss the kinetic
structure of the magnetopause of both planets, its global characteristics and the
effects on the interaction between the planetary plasma and the solar wind. A Vlasov
equilibrium model is constructed for both planetary magnetopauses and provides
good estimates of the magnetic field profile across the interface. The model is also
in agreement with plasma data and evidence the role of planetary and solar wind
ions on the spatial scale and equilibrium of the magnetopause of the two planets. |
