We investigate the effect of microscopic three-body forces on the {sup 3}P F{sub 2} neutron superfluidity in neutron matter, {beta}-stable neutron star matter, and neutron stars by using the BCS theory and the Brueckner-Hartree-Fock approach. We adopt the Argonne V18 potential supplemented with a microscopic three-body force as the realistic nucleon-nucleon interaction. We have concentrated on studying the three-body force effect on the {sup 3}P F{sub 2} neutron pairing gap. It is found that the three-body force effect considerably enhances the {sup 3}P F{sub 2} neutron superfluidity in neutron star matter and neutron stars.
