Monte-Carlo simulation of neutral atoms trajectories in the solar system

  • Yu. G. Malama


The Monte-Carlo simulation of the neutral interstellar atoms penetration into the solar system is considered. The ionization and charge exchange processes with due regard for the plasma interface structure as well as the gravitational force and the radiation pressure are taken into account. The Monte-Carlo scheme with splitting of atom trajectories is developed, and its high efficiency is shown against the imitation Monte-Carlo scheme. The main algorithms of the splitting scheme and the possible applications of the suggested method are described. In particular calculation of the mass, momentum and energy sources appearing in the plasma gasdynamical equations is considered. The gasdynamical approach for these terms is shown to be inconsistent with the Monte-Carlo results.
