Description

Neutrino absorption and emission (the "Urca process") is an essential aspect of the formation and cooling of neutron stars and of neutron star mergers. In this talk I will describe the traditional way of calculating Urca rates, explain its shortfalls, and propose an alternative approach, the nucleon width approximation.
