Global Venus Solar Wind Coupling and Oxygen Ion Escape

Fedorov, A.; Barabash, S.; Futaana, Y. +5 more

The present day Venusian atmosphere is dry, yet, in its earlier history a significant amount of water evidently existed. One important water loss process comes from the energy and momentum transfer from the solar wind to the atmospheric particles. Here, we used measurements from the Ion Mass Analyzer onboard Venus Express to derive a relation betw…

Magnetic Topology at Venus: New Insights Into the Venus Plasma Environment

Xu, Shaosui; Frahm, Rudy A.; Luhmann, Janet G. +2 more

This study provides the first characterization of magnetic topology (i.e., the magnetic connectivity to the collisional ionosphere) at Venus, which might give new insights into the Venusian space environment on topics such as the penetration of the interplanetary magnetic field (IMF) into the ionosphere, planetary ion outflow and inflow, and auror…
