The cases of singlet-state pairing with isotropic superfluid gap and triplet-state pairing with anisotropic gap are analysed. The neutrino emission due to singlet-state pairing of protons is found to be greatly suppressed with respect to the cases of singlet- and triplet-state pairings of neutrons. The neutrino emission due to pairing of neutrons is shown to be very important in the superfluid neutron-star cores with the standard neutrino luminosity an","authors_text":"A.D. Kaminker, D.G.
