Lindblom, L. ; Detweiler, S. Abstract The neutrino radiation, trapped in the core of a collapsing star, serves as an efficient mechanism for transporting energy and momentum throughout the core. It is shown however, that the associated radiative viscosity is ineffective in damping differential rotation in the stellar core. The effectiveness of damping the oscillations of a stellar core by neutrino dissipation and by gravitational radiation is compared. Gravitational radiation will provide the dominant damping mechanism for the low l modes in sufficiently dense stellar cores rho at least 10 to the 13th power. Neutrino dissipation provides the damping for lower density cores, and for modes with higher l values. Our estimates indicate that neutrinos do not dominate the damping of core oscillations to the extent found by Kazanas and Schramm.
