Force Analysis of Venus's Induced Magnetosphere: A Multifluid Hall–Magnetohydrodynamics Study

Cao, Jinbin; Ge, Yasong; Lu, Haoyu +8 more

Understanding which processes control atmospheric escape and the loss of water from planetary environments is crucial. The ESA's Venus Express spacecraft has observed a significant depletion in Venus's upper atmosphere, driven by the solar wind. In such scenarios, the electromagnetic force can accelerate planetary ions to energies that allow them …

Similarities and Differences between ICME-driven Shocks Observed by VEX (∼0.72 au) and WIND (∼1.0 au)

Xu, Qi; Feng, Xueshang; Shen, Zhenning +7 more

The features of interplanetary shocks driven by interplanetary coronal mass ejections (ICMEs) observed by WIND (∼1.0 au) and Venus Express (VEX; ∼0.72 au) during the same period are statistically analyzed by comparing their similarities and differences. It is found that the proportion of ICME-driven shocks in all shocks decreases slightly from ∼0.…
