“…So planetary magnetosphere is less important in this case. A magnetospheric plasma shell which exists around some planets have been investigated by many authors [8][9][10][11][12][13][14].We have considered a homogeneous plasma [15], [16] comprised of electrons and ions. The basic governing equations for the fluid model are as follows [17,18,20,21,48]:…”

Two-stream plasma instability as a potential mechanism for particle escape from the Venusian ionosphere

et al. 2022

In this work we investigate the possibility of two-stream instability in the Venusian atmosphere to lead to momentum transfer to subsequent escape of Hydrogen and Oxygen ions from the ionosphere. We employ the hydrodynamic model and obtain the linear dispersion relation from which the two-stream instability is studied. Further the interaction of solar wind with the ions of Venus ionosphere from which the instability sets in, has been studied with the data from ASPERA-4 of Venus Express (VEX). The data supports the fact that the two-stream instability can provide sufficient energy to accelerate ions to escape velocity of the planet.
