鉴于近期的观测数据更倾向于大质量的中子星，通过相对论平均场理论和相关弱作用理论来研究大质量中子星内部中微子发射性质及星体的冷却曲线。计算结果表明大质量中子星的冷却性质与星体质量有关，但是具体的变化规律还取决于模型参数。%Since the latest astronomical observations favored neutron stars with the mass of about 2Msol ( Msol is the solar mass ) , we study the neutrino emitting from massive neutron stars , as well as the cooling curves of stars , using the relativistic mean field theory and relevant weak interactional theories .Results show that the cool-ing properties of massive neutron stars are not only related to the masses of stars , but also depend on both the models and parameter sets .
