Abstract
The stability of accretion shocks in magnetic white dwarfs is investig ated. Shock oscillations are simulated numerically, and in the simulat ions bremsstrahlung and cyclotron cooling are considered in an explici t form. We have found that for shocks with magnetic fields lower than 10 MG, shock oscillations can be sustained; while for magnetic fields greater than 20 MG, the oscillations are suppressed.
