| Abstract: | A new set of nucleon coupling constants (CZ11) is obtained for the relativistic mean field (RMF) theory based on the recent
experimental information on the symmetry energy derived from the data from NSCL/MSU. The surface gravitational redshift of
a proto neutron star (PNS) is examined within the RMF framework for the baryon octet system by using this set of parameters.
It is found that the surface gravitational redshift for CZ11 is smaller than that for GL97. For the CZ11 parameter set, the
surface gravitational redshift of a PNS at T=15 MeV is smaller than that at T=0 MeV. It is also found that the surface gravitational redshift corresponding to M
max/R for the CZ11 parameter set is smaller by about 10 percent than that for GL97, with M
max being the maximum mass and R being the corresponding radius. |
