Interaction of the neutral interstellar component with the heliosphere

The global dynamics of the neutral H, He, O, Ne, and C components in the he liosphere plays a vital part in the interaction of the local interstellar m edium (LISM) with the solar wind. In this paper, a particle-mesh method is used to solve the Boltzmann equation. This method takes into account the di rect and reverse charge-exchange processes, photoionization, and gravitatio n forces. The results of this incompletely self-consistent simulation of th e dynamics of atoms and ions are discussed in the present paper.
