Gas Dynamic Models of the Interaction between the Solar Wind and Cometary Atmospheres

Baranov, V. B.

Gas dynamic models of the interaction between the solar wind and cometary atmospheres are considered. Interest in the development of such models arose sharply after the beginning of the investigations of comets with the use of spacecraft launched at distances close to their surfaces. The instruments on this spacecraft gave the possibility to inves…

Three-dimensional magnetohydrodynamic model of the interaction between the solar wind and cometary atmospheres

Baranov, V. B.; Alexashov, D. B.; Lebedev, M. G.

A magnetohydrodynamic (MHD) model of the interaction between the solar wind and an expanding gas flow issuing from a comet nucleus is presented. The processes of photoionization of the neutral component of the comet matter and the resonance charge exchange between charged and neutral particles are taken into account, together with the interplaneta…
