Mathematical Modelling of Shock Wave Interaction with Compact Gravitating Object

Forming of erupting envelope of a star in binary stellar system and its interaction with the second star considering as compact solid sphere are investigated numerically by 2D hydrodynamical non-stationary model. In vicinity of the first star it was constructed completely conservative difference scheme based on mass Lagrange coordinates, as well as near the second star it was utilized Eulerian difference scheme. The influence of the main problem parameters (such as the eruption energy and angular revolution velocity of the binary system) on the flow was investigated.
