Seminar: Solar Wind Interaction with Venus Upper Atmosphere - A Hall Multi-Fluid MHD model

Nihan Chen (Beihang University, Beijing, PR China) will give a presentation on the interaction between the solar wind and the upper atmosphere of Venus, as simulated using a Hall Multi-Fluid Magnetohydrodynamic (MHD) model. The talk will highlight key physical processes, model dynamics, and implications for planetary space weather and atmospheric escape.

Unlike Earth, Venus does not have a magnetic field to shield it from the solar wind—a stream of charged particles constantly blowing from the Sun. In this study, we use a computer simulation that models the behavior of different types of charged ions around Venus in three dimensions. This allows us to explore how Venus's space environment responds to different solar wind conditions. We examine changes in the upper atmosphere, the shifting positions of plasma boundaries around the planet, and how heavier particles from Venus's atmosphere escape into space. This model could serve as an efficient tool for studying ion-scale processes and may have applications in investigating the impact of individual upstream conditions on the induced magnetic field and ion dynamics.
