Rapid Spin Deceleration of Magnetized Proto-Neutron Stars via Asymmetric Neutrino Emission
arXiv:1301.7495 · doi:10.1103/PhysRevC.89.035801
Abstract
We calculate the spin deceleration of proto-neutron stars by asymmetric neutrino absorption in the context of a fully relativistic mean field theory. We calculate for the first time the spin deceleration of neutron stars due to asymmetric neutrino absorption in a toroidal magnetic field configurations. We find a surprising effect that the deceleration can much larger for asymmetric neutrino absorption in a toroidal magnetic field than the usually presumed braking due to magnetic dipole radiation. This may explain the observation that magnetars appear to have had a more rapid deceleration in the past.
