Neutrino oscillation mechanism for pulsar kicks reexamined
arXiv:astro-ph/0206471 · doi:10.1103/PhysRevD.66.123005
Abstract
Anisotropic neutrino emission during the neutron star formation can be the origin of the observed proper motions of pulsars. We derive a general expression for the momentum asymmetry in terms of the neutrino energy flux gradient, and show that a nonvanishing effect is induced at the lowest order by a deformed neutrinosphere. In particular, this result is valid for a neutrino flux transported through a spherical atmosphere with constant luminosity.
