Genesis of magnetic fields in isolated white dwarfs

Briggs, Gordon; Ferrario, Lilia; Tout, Christopher; Wickramasinghe, Dayal

Description

A dynamo mechanism driven by differential rotation when stars merge has been proposed to explain the presence of strong fields in certain classes ofmagnetic stars. In the case of the highfield magnetic white dwarfs (HFMWDs), the site of the differential rotation has been variously thought to be the common envelope, the hot outer regions of a merged degenerate core or an accretion disc are formed by a tidally disrupted companion that is subsequently accreted by a degenerate core. We have shown...[Show more]
