摘要：

We calculate properties of neutron stars such as mass and radius using a relativistic Dirac-Brueckner-Hartree-Fock approach. Modern meson-exchange potential models are used to evaluate the G matrix for asymmetric nuclear matter. For pure neutron matter we find the maximum mass to be Mmax2.4M for a radius R12 km, whereas with a proton fraction of 30% we find Mmax2.1M for a radius R10.5 km, close to the experimental values. The implications are discussed. © 1994 The American Physical Society.
