Abstract
Neutrino oscillations, biased by the magnetic field, alter the shape o f the neutrinosphere in a cooling protoneutron star emerging from the supernova collapse. The resulting anisotropy in the momentum of outgoi ng neutrinos can be the origin of the observed proper motions of pulsa rs. The connection between the pulsar velocities and neutrino oscillat ions results in a prediction for the tau neutrino mass of m(nu(tau)) s imilar to 100 eV.
