摘要

The influence of the σ*andΦmesons on the surface gravitational redshift of a proto neutron star is investigated within the framework of relativistic mean field theory for the baryon octet {n,p,A,∑-,∑0,∑+,∑-,∑0} system.It is found that,compared with those without considering the contribution of σ*and()mesons,the surface gravitational redshift decreases,corresponding to the maximum value of the mass decreasing from 0.2220 to0.1937,about 12.7%.
