    "abstract": "The equation of state (EOS) of dense matter and neutrino mean free path\n(NMFP) in a neutron star have been studied by using relativistic mean field\nmodels motivated by effective field theory (ERMF). It is found that the models\npredict too large proton fractions, although one of the models (G2) predicts an\nacceptable EOS. This is caused by the isovector terms. Except G2, the other two\nmodels predict anomalous NMFP. In order to minimize the anomaly, besides an\nacceptable EOS, a large M* is favorable. A model with large M* retains the\nregularity in the NMFP even for a small neutron fraction.",
