The mechanism responsible for the formation of magnetars? The study: “Spatially resolved X-ray study of supernova remnants that host magnetars: Implication of their fossil field origin” of P. Zhou (University of Amsterdam/Nanjing University) recently appeared on A&A
At the end of their evolution, stars with a final mass larger than 8 solar masses (“final mass” because massive stars lose a large fraction of their mass as stellar winds during their evolution) explode as Core-Collapse Supernovae, e.g. triggered by the collapse of their nucleus. Two objects are produced by such explosions: the supernova remnant formed by the ejected
