英文摘要:
Properties of nuclear matter and neutron star are described in relativistic mean field theory with density-dependent effective interactions. The difference of saturated properties for nuclear matter between different effective interactions is subtle except for NL2 and TM2 which are mainly used for light nucleus. For neutron star matter, the meson field potentials calculated from different effective interactions have short odds at low-density, while the difference becomes large at high-density and increases with density. The equations of state (EOS) of neutron star given by density-dependent effective interactions DD-ME1 and TW-99 are softer than those of the other effective interactions such as NL1, NL3 and NLSH. The maximum masses calculated from different EOS are 2.0-3. OMcircle dot , and the corresponding radius are 10-14km.
