Kinetic study of ion acoustic waves in Venusian ionosphere
Lakhina, G. S.; Kamalam, T.; Singh, S. V. +1 more
Kinetic dispersion of the ion acoustic waves has been explored for an unmagnetized five component plasma system comprising of Venusian protons, Venusian oxygen ions, Venusian electrons, solar wind protons, and kappa electrons. The solar wind protons and electrons are assumed to be streaming along the ambient magnetic field. The plasma parameters f…
Evolution of Kelvin-Helmholtz instability at Venus in the presence of the parallel magnetic field
Zhang, T. L.; Cao, J. B.; Fu, H. S. +2 more
Two-dimensional MHD simulations were performed to study the evolution of the Kelvin-Helmholtz (KH) instability at the Venusian ionopause in response to the strong flow shear in presence of the in-plane magnetic field parallel to the flow direction. The physical behavior of the KH instability as well as the triggering and occurrence conditions for …
