Abstract:Stars of spectral types O and B produce neutron stars (NSs) after supernova explosions. Most of NSs are strongly magnetised including normal radio pulsars with π΅ β 10 12 G and magnetars with π΅ β 10 14 G. A fraction of 7-12 per cent of massive stars are also magnetised with π΅ β 10 3 G and some are weakly magnetised with π΅ β 1 G. It was suggested that magnetic fields of NSs could be the fossil remnants of magnetic fields of their progenitors. This work is dedicated to study this hypothesis. First, we gather … Show more
