Context. The photospheres of about 5–10% of the upper main sequence stars exhibit remarkable chemical anomalies. Many of these chemically peculiar (CP) stars have a global magnetic field, the origin of which is still a matter of debate. Aims. We present a comprehensive statistical investigation of the evolution of magnetic CP stars, aimed at providing constraints to the theories that deal with the origin of the magnetic field in these stars. Methods. We have collected from the literature data… Expand

A fossil origin for the magnetic field in A stars and white dwarfs
TLDR
Numerical simulations show that stable magnetic field configurations, with properties agreeing with those observed, can develop through evolution from arbitrary, unstable initial fields, establishing fossil fields as the natural, unifying explanation for the magnetism of all these stars. Expand
