Monte Carlo study of interaction between solar wind plasma and Venusian upper atmosphere

Barabash, S.; Stenberg, G.; Shematovich, V. I. +1 more

Isolated events of proton and alpha particle precipitation in the Venusian atmosphere were recorded with the use of the ASPERA-4 analyzer on board the ESA Venus Express spacecraft. Using a Monte Carlo simulation method for calculation of proton and alpha particle precipitations in the Venusian atmosphere, reflected and upward directed particle flu…

The estimate of the Venus magnetotail length

Popov, V. Yu.; Zelenyi, L. M.; Vasko, I. Yu.

We consider the process of flux tubes straightening in the Venus magnetotail on the basis of MHD model. We estimate the distance x _t, where flux tubes are fully straightened due to the magnetic tension and the magnetotail with the characteristic geometry of field lines ("slingshot" geometry) ends. We investigate the influence of the tra…
