Description

In this talk I will revisit modified and direct Urca
processes in nuclear matter under conditions that we expect in neutron
star mergers. Nuclear Urca processes have shown to be a potential
significant source of bulk viscosity under merger conditions. I will
explain how a correct relativistic treatment can alter the rates and
the true beta equilibrium significantly, and present a new way to deal
with in-medium effects for modified Urca.
