Abstract: We investigate the momentum given to a protoneutron star, the pulsar kick,during the first 10 seconds after temperature equilibrium is reached. Using amodel with two sterile neutrinos obtained by fits to the MiniBoone and LSNDexperiments there is a large mixing angle, and the effective volume foremission is calculated. Using formulations with neutrinos created by URCAprocesses in a strong magnetic field, so the lowest Landau level has a sizableprobability, we find that with known paramenters the asymmetric sterileneutrino emissivity might account for large pulsar kicks.
