- Аннотация: It is well known that cosmic rays interact with plasma flow through their scattering by magnetohydrodynamic waves. Therefore, of interest is the influence of Galactic cosmic rays (GCR) on the solar-wind flow. For a spherically symmetric solar wind, this problem was considered by Ko and Webb (1987, 1988). However, the local interstellar medium and the Sun are known to move relative to each other at supersonic speed. As a result, the spherical symmetry of the solar wind breaks down. In this work, we estimate the effect of GCR on the structure of the heliosphere for supersonic flow of the solar wind over the local interstellar medium. For this purpose, the problem of GCR propagation in the outer heliosphere is considered for various diffusion coefficients. This paper is the first step on the road to constructing a model of interaction of a three-component (plasma, atoms, cosmic rays) interstellar medium with the solar wind.
