1S0 proton and neutron superfluidity in β-stable neutron star matter

Abstract We investigate the effect of a microscopic three-body force on the proton and neutron superfluidity in the 1 S 0 channel in β -stable neutron star matter. It is found that the three-body force has only a small effect on the neutron 1 S 0 pairing gap, but it suppresses strongly the proton 1 S 0 superfluidity in β -stable neutron star matter.
