AI 中文摘要
我们研究相对论平均场（RMF）理论中的有效质量对坍缩驱动超新星中心核性质及致密天体形成的影响。迄今为止，有效质量的影响仅在非相对论框架下被研究。为阐明相对论框架下有效质量与非相对论框架的差异，我们采用RMF理论中参数化方案TM1e和TM1m的物态方程（EOS）表，二者具有相同的饱和性质但有效质量不同。结果表明，超新星物质中有效质量的选择会通过压强影响EOS的刚度，并通过温度影响热力学行为。我们通过对大质量恒星的引力坍缩与反弹、原中子星冷却开展一系列数值模拟，探究中微子发射下的物质演化差异。具有大有效质量的EOS因刚度低，会形成致密的原中子星，并在高密度高温下早期坍缩为黑洞；这会导致原中子星冷却阶段的长时高能中微子发射，以及黑洞形成时的短时高能中微子爆发。
英文摘要
We study the influence of the effective mass in the relativistic mean field (RMF) theory on the properties of the central core of collapse-driven supernovae and the formation of compact objects. Influence of the effective mass has been so far studied within the non-relativistic frameworks. In order to clarify the role of the effective mass in the relativistic frameworks, which is different from non-relativistic ones, we adopt the set of equation of state (EOS) tables using the parameterizations TM1e and TM1m, which have different effective masses but with the same saturation properties, in the RMF theory. We show that choices of the effective mass in supernova matter affect both the stiffness of the EOS through pressure and the thermodynamical behavior through temperature under the RMF frameworks. We explore differences in matter evolution with neutrino emissions by performing a set of numerical simulations of the gravitational collapse and bounce of massive stars and the cooling of the proto-neutron stars. The EOS with large effective mass leads to compact proto-neutron stars and early collapse to black holes with high densities and temperatures due to the softness. It leads to high energy neutrinos in long emission from the proto-neutron star cooling and in short burst from the black hole formation.
