Abstract We investigate the 3PF2 neutron superfluidity in $\beta$-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 3PF2 neutron pairing gap. It is found that the three-body force effect is to enhance remarkably the 3PF2 neutron superfluidity in neutron star matter and neutron stars.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
