Superfluidity in beta-stable neutron star matter

Abstract

In this work we present results for pairing gaps in $\beta$--stable neutron star matter with electrons and muons using a relativistic Dirac--Brueckner--Hartree--Fock approach, starting with modern meson--exchange models for the nucleon--nucleon interaction. Results are given for superconducting ${}^1{S}_0$ protons and ${}^3{P}_2$ and ${}^1{D}_2$ neutron superfluids. A comparison is made with recent non--relativistic calculations and the implications for neutron star cooling are discussed.
