论文摘要
我们回顾了相对论均值场方法中中子恒星在有限温度下的中子恒星的组成和方程。我们利用新的FSU2H*模型，该模型根据XI原子的最新分析来改善XI电位，建立在FSU2H方案上，我们将其扩展为包括有限温度校正。计算是针对多种密度，温度和电荷分数进行的，从而探索了在原始恒星，二元合并残留物和超新星爆炸中发现的不同条件。在有限温度下的组合物和状态方程的包含很大，因此，这将导致热中子恒星的性质和进化发生显着变化。
We review the composition and the equation of state of the hyperonic core of neutron stars at finite temperature within a relativistic mean-field approach. We make use of the new FSU2H* model, which is built upon the FSU2H scheme by improving on the Xi potential according to the recent analysis on the Xi atoms, and we extend it to include finite temperature corrections. The calculations are done for a wide range of densities, temperatures and charge fractions, thus exploring the different conditions that can be found in protoneutron stars, binary mergers remnants and supernovae explosions. The inclusion of hyperons has a strong effect on the composition and the equation of state at finite temperature, which consequently would lead to significant changes in the properties and evolution of hot neutron stars.
