Effect of the solar wind on the nature of arbitrary amplitude ion-acoustic solitary waves in Venus' upper ionosphere

Fichtner, H.; Lazar, M.; El-Shafeay, N. A. +5 more

Observations suggest that at altitudes of 1000-2000 km the interaction between the solar wind and Venus' ionospheric plasma leads to ion-acoustic waves (IAWs) formation. For studying this hypothesis, a suitable hydrodynamic model relying on the observational data from Pioneer Venus Orbiter (PVO) and Venus Express (VEX) is developed. It consists of…
