A magnetic dynamo driven by differential rotation generated when stars merge can explain strong fields in certain classes ofmagnetic stars, including the high fieldmagnetic white dwarfs (HFMWDs). In their case the site of the differential rotation has been variously proposed to be within a common envelope, the massive hot outer regions of a merged degenerate core or an accretion disc formed by a tidally disrupted companion that is subsequently incorporated into a degenerate core. We synthesize...[Show more]
