Numerical studies of wind accretion using SPH I. 2D simulations.
Abstract
Two-dimensional numerical simulations of accretion by a gravitating object from a homogeneous wind are performed using SPH. The effects of several parameters changes as well as the algorithm modifications are studied. The flow is in most cases weakly unstable with a very small, quasi-periodic oscillation of the shock cone. Comparison with previous works is also done.
