Effects of σ* and φ on the proto-neutron star PSR J0348+0432

The influence of sigma* and phi on the proto-neutron star (PNS) PSR J0348+0432 is described by the relativistic mean field theory (RMFT) through choosing effective coupling constants. We use an entropy per baryon S = 1 to describe the thermal effects on PSR J0348+0432 in this work and compare this PNS with and without sigma*, phi. These effects include the particle number distribution, mass-radius relation, moment of inertia and surface gravitational redshift. The PNS PSR J0348+0432 with sigma* and phi has more nucleons and will push forward the threshold for the appearance of the hyperons. The mass-radius relations are (2.010M(circle dot), 12.6520 km) with sigma* and phi and (2.010M(circle dot), 12.6170 km) without sigma* and phi. The moments of inertia corresponding to PNS PSR J0348+0432 are (2.010M(circle dot), 1.510x10(45) g.cm(2)) and (2.010M(circle dot), 1.559x10(45) g.cm(2)) respectively, and the surface gravitational redshifts are (2.010M(circle dot), 0.3747) and (2.010M(circle dot), 0.3701) respectively. With the help of these calculations, we study the restriction of sigma* and phi on the interactions between baryons in the PNS core.
