| Zusammenfassung |
| We study the solar wind induced escape of the ionic hydrogen and oxygen from Venus. This non-thermal atmospheric erosion process has been observed in detail by the Venus Express spacecraft in recent years. We use our global hybrid simulation (HYB-Venus) to study properties of the escaping planetary ions, concentrating on the escape rates and energization processes. In the simulation the planetary ions include the thermal and hot populations of the H+ and O+ species. Especially, we study how the relative escape fluxes and energies of the two species vary with regions of the Venusian induced magnetosphere. |
