Abstract
A small asymmetry in the flux of neutrinos emitted by a hot newly-born neutron star could explain the observed motions of pulsars. However, even in the presence of parity-violating processes with anisotropic sc attering amplitudes, no asymmetry is generated in thermal equilibrium. We explain why this no-go theorem stymies some of the proposed explan ations for the pulsar ''kick'' velocities. (C) 1998 Elsevier Science B .V. All rights reserved.
