Abstract

We study the cooling of isolated neutron stars. The main cooling regulators are introduced: equation of state (EoS), thermal transport, heat capacity, neutrino and photon emissivity, superfluid nucleon gaps. The neutrino emissivity includes the main processes. A strong impact of medium effects on the cooling rates is demonstrated. Taking into account medium effects on reaction rates and on nucleon superfluid gaps modern experimental data can be well explained.
