Formation of a neutron star with a strong magnetic field during the collapse may lead to the violation of the mirror symmetry and formation of an asymmetric magnetic field. The dependence of the weak interaction cross-section on the magnetic field strength leads to asymmetric neutrino flux and formation of rapidly moving pulsars (due to the recoil action) as well as rapidly moving black holes.
A 1993 study studied this question.
