Surface distribution of accretion zones on white dwarfs in polars
Abstract
Using 3D numerical simulations we investigate the flow structure in polars and its dependence on the magnetic field of the accretor. We demonstrate that the accreting material is splited into two flows towards the opposite magnetic poles of the accretor. The ratio between these fluxes depends on the magnetic field and is going to unity with the increasing of the magnetic strength. The localization of the accretion zones on the surface of the accretor depends also on the magnetic field strength. In strong field, these zones follow the magnetic poles while they are slightly shifted in weaker field.
