Self-consistent model of the solar wind interaction with two-component circumsolar interstellar cloud: Mutual influence of thermal plasma and galactic cosmic rays

The interaction of the solar wind with the two-component interstellar mediu m consisting of thermal plasma and galactic cosmic rays is studied numerica lly using a soft fitting technique based on the high-resolution Godunov sch eme and the physical process splitting method. Mutual influence of plasma a nd cosmic ray components on the solar wind termination is considered. It is shown that cosmic rays can considerably modify the shape and structure of the solar wind termination shock and the bow shock, and change the position s of the heliopause and bow shock if no H atoms are taken into account.
