    "abstract": "Asymmetric nuclear matter is treated in the formalism of Dirac-Brueckner\napproach with Bonn one-boson-exchange nucleon-nucleon interaction. We extract\nthe symmetry energy coefficient at the saturation to be about 31 MeV, which is\nin good agreement with empirical value of $30\\pm 4$ MeV. The symmetry energy is\nfound to increase almost linearly with the density, which differs considerably\nfrom the results of non-relativistic approaches. This finding also supports the\nlinear parameterization of Prakash, Ainsworth and Lattimer. We find,\nfurthermore, that the higher-order dependence of the nuclear equation of state\non the asymmetry parameter is unimportant up to densities relevant for neutron\nstars. The resulting equation of state of neutron-rich matter is used to\ncalculate the maximum mass of neutron star, and we find it to be about\n2.1$M_\\odot$. Possible mechanisms for the softening of the equation of state\nare also discussed.",
