Is there evidence for field restructuring or decay in accreting magnetic white dwarfs?

Zhang, C M; Wickramasinghe, Dayal; Ferrario, Lilia

Description

The evolution of the magnetic field of an accreting magnetic white dwarf with an initially dipolar field at the surface has been studied for non-spherical accretion under simplifying assumptions. Accretion on to the polar regions tends to advect the field toward the stellar equator which is then buried. This tendency is countered by Ohmic diffusion and magnetohydrodynamic instabilities. It is argued that if matter is accreted at a rate of and the total mass accreted exceeds a critical value...[Show more]
