✦ Synopsis

For neiitrori stjars with hyperon-mixed core, neutrino emissivity is studied under the equation of state, obtained by introducing three-body force universal for all baryons so as to assure the maximum mass compatible with the observation. By paying attention t o tlic density dependence of the critical temperatures of the baryon superfluids, which reflect the nature of baryon-baryon interaction and control neutron star cooling, we sliow whatJ neutrino emission processes are efficient in the regions with and without hyperon mixiiig and rerriark i t s iinplications related to neutron star cooling.
