Origin of PSRs with 0.1 < P < 0.3 s and 5 x 1E5 < Tau < 1E7 yr after the second Supernova explosion in HMXBs

Abstract

The origin of a part of the single pulsars with relatively low magnetic fields B < 1E12 G and with characteristic times Tau < 1E7 yr is established. Such pulsars occur as a result of the disruption of High Mass X-ray Binary Systems after a second Supernova explosion. In these binaries mass accretion onto the surface of X-ray pulsars leads to the decrease of the magnetic field from its initial value B ~ 1E12-1E13 G down to B < 1E12 G similar to the processes in Low Mass X-ray Binaries.
