Abstract
We demonstrate that there exists a new mechanism for dissipating the energy of stellar oscillations. For neutron stars, in particular, we show that the mechanical energy of density perturbations is not only dissipated to heat via bulk viscosity, but also that energy is radiated away via neutrinos. This energy dissipation will be associated with a viscosity coefficient, the radiative viscosity, which is larger than the bulk viscosity in the case of non-strange quark matter and nuclear matter.
