PULSAR KICKS WITH STANDARD AND STERILE NEUTRINOS AND LANDAU LEVELS

Abstract

I first give an update on our study of the energy asymmetry given the proto-neutron star during the time when the neutrino sphere is near the surface of the proto-neutron star, at a time 10-20s, using the modified URCA process. With the magnetic field strong enough for a large fraction of the electrons produced with the anti-neutrinos to be in the lowest Landau level, we predict a pulsar velocity of 1.03 × 10−4(T/1010K)7 km / s , which reaches 1000 km/s if T ≃ 9.96 × 1010 K . Also, using the recent results of the MiniBoone study, with two sterile neutrinos, I give results for pulsar kicks during the first 10s.
