| Popis: | In the relativistic mean field theory and cooling theories, relativistic correction on neutrino emission from neutron stars in four typical nuclear parameter sets, GM1, GL85, GPS250 and GPS300 is studied. Results show that relativistic effect makes the neutrino emissivity, neutrino luminosity and cooling rate lower, compared with the non-relativistic case. And the influence of relativistic effect grows with the mass of the neutron star. GPS300 set leads to the biggest fall in neutrino emissivity, whereas GM1 set leads to the largest disparity in cooling rate caused by relativistic effect. |
