# Expanded calculation of weak-interaction-mediated neutrino cooling rates due to 56Ni in stellar matter

@article{Nabi2010ExpandedCO, title={Expanded calculation of weak-interaction-mediated neutrino cooling rates due to 56Ni in stellar matter}, author={Jameel-Un Nabi}, journal={Physica Scripta}, year={2010}, volume={81}, pages={025901} }

An accurate estimate of the neutrino cooling rates is required in order to study the various stages of stellar evolution of massive stars. Neutrino losses from proto-neutron stars play a crucial role in deciding whether these stars would be crushed into black holes or explode as supernovae. Both pure leptonic and weak-interaction processes contribute to the neutrino energy losses in stellar matter. At low temperatures and densities, the characteristics of the early phase of presupernova…
