Abstract
We investigate the stability of wind accretion in a two-dimensional fr ame. We employ high-resolution numerical methods with dynamic mesh-ref inement for the integration of the hydrodynamic equations. Attention i s paid to well adapted physical and numerical boundary conditions. Whe n comparing our results with earlier studies we point to correlations between the size of the accreting object and the onset of flip-flop in stabilities.
