论文摘要
我们提出了新颖的有限温度FSU2H $^*$状态模型，该模型涵盖了原始恒星，中子星和超新星的各种温度和轻子级分。当考虑了超声波自由度时，温度对热力学可观察物的影响和中子星核的组成更强。我们特别注意在存在Hyperos的情况下热指数的温度和密度依赖性，并得出结论，使用常数$γ$定律无法再现真正的热效应。
We present the novel finite-temperature FSU2H$^*$ equation-of-state model that covers a wide range of temperatures and lepton fractions for the conditions in proto-neutron stars, neutron star mergers and supernovae. The temperature effects on the thermodynamical observables and the composition of the neutron star core are stronger when the hyperonic degrees of freedom are considered. We pay a special attention to the temperature and density dependence of the thermal index in the presence of hyperons and conclude that the true thermal effects cannot be reproduced with the use of a constant $Γ$ law.
