Scientific paper

The properties of infinite nuclear matter and neutron stars are studied theoretically in a relativistic mean-field (RMF) approach with three typical parameter sets NL1, NL-SH and TM1. It is found that all these new RMF parameter sets can very satisfactorily reproduce the properties of high density matter. Among these parameter sets, TM1, with a nonlinear ω term, reproduces a slightly smaller energy, pressure and neutron star mass than NL-SH and NL1. The ρ meson field has a large influence on the properties of a neutron star and infinite nuclear matter. A detailed discussion for the significance of numerical results is also given.
