The magnetic field clock angle departure in the Venusian magnetosheath and its response to IMF rotation

Xu, Qi; Zhang, Tielong; Rong, Zhaojin +4 more

We investigate the characteristics of interplanetary magnetic field (IMF) draping in the Venusian magnetosheath using both Venus Express (VEX) observations and magnetohydrodynamics simulations. The distributions of magnetosheath field clock angle illustrate the nearly symmetric morphology of draped magnetic field with respect to the solar wind ele…

Determination of the eddy diffusion in the Venusian clouds from VeRa sulfuric acid observations

Sheng, Zheng; Dai, Longkang; Shao, Wencheng +1 more

Context. The vertical eddy diffusion coefficient (K_zz) characterizing the efficiency of vertical atmospheric mixing is essential for 1D planetary atmospheric modeling, but poorly constrained in the Venusian clouds, where our ability to observe tracer gases is limited. The Venusian clouds are mainly composed of H₂SO₄

Linear and nonlinear kinetic Alfvén waves at Venus

Fichtner, H.; Lazar, M.; Moslem, W. M. +1 more

Space observations show that Venus suffers significant atmospheric erosion caused by the solar wind forcing. Plasma acceleration is found to be one of the main mechanisms contributing to the global atmospheric loss at Venus through its magnetotail. Motivated by these observations, we propose that kinetic Alfvén waves (KAW) may be a possible candid…
