Magnetic fields in interacting binaries

23 Apr 2018

(2015) have proposed that the strong magnetic fields observed in some single white dwarfs (MWDs) are formed by an α-Ωdynamo driven by differential rotation when two stars, the more massive one with a degenerate core, merge during common envelope (CE) evolution (Ferrario et al., 2015b). We synthesise a population of binaries to investigate if fields in the magnetic cataclysmic variables (MCVs) may also originate during stellar interaction in the CE phase.
