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

The influence ofσ~*andφon 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 withoutσ~*,φ.These effects include the particle number distribution,mass-radius relation,moment of inertia and surface gravitational redshift.The PNS PSR J0348+0432 withσ~*andφhas more nucleons and will push forward the threshold for the appearance of the hyperons.The mass-radius relations are(2.010M,12.6520 km)withσ~*andφand(2.010M,12.6170 km)withoutσ~*andφ.The moments of inertia corresponding to PNS PSR J0348+0432are(2.010M,1.510×10~(45)g·cm~2)and(2.010M,1.559×10~(45)g·cm~2)respectively,and the surface gravitational redshifts are(2.010M,0.3747)and(2.010M,0.3701)respectively.With the help of these calculations,we study the restriction ofσ~*andφon the interactions between baryons in the PNS core.
