On the model of the solar wind-interstellar medium interaction with two shock waves

The model of the solar wind interaction with interstellar medium suggested by Baranov et al. (1970) is developed. In this model (TSM) the presence of two shock waves is assumed, through which the solar wind and interstellar gas pass, the latter moving relative to the Sun at supersonic speed (20km s-1). The distance between shocks was considered earlier (Baranov et al., 1970; Baranov and Krasnobaev, 1971) to be small compared with their distance from the Sun, due to the hypersonic character of the flow. The structure of the subsonic flow portion may not be taken into account. In the present paper the distribution of the gas parameters in the region between shocks is calculated which, in particular allows the estimation of the possibility of its experimental detection, observing radio-scintillation on interstellar irregularities (Baranov et.al., 1975). The possible influence on the model of galactic hydrogen neutral atoms penetrating into interplanetary medium is estimated. (Auth.)
