Mixed phase in the first-order phase transition of nuclear matter at finite temperature

我们探索了与超新星核心有关的核物质的性质和结构。特别是对气液混合相的出现进行了详细的研究。考虑强子-夸克混合相，研究了Urca过程对中子星的冷却过程。我们成功地解释了Cas A中子星星的冷却，修正了高密度强子-夸克混合相模型，成功地解释了质量和半径为太阳质量两倍的中子星星。

We have explored the properties and structures of nuclear matter relevant to the core of supernovae. Particularly, the appearance of mixed phase of liquid and gas was studied in detail. The cooling process of neutron stars by the Urca process was studied by considering hadron-quark mixed phase. We succeeded in explaining the cooling of Cas A neutron star.We have revised our model of hadron-quark mixed phase at high density and succeeded in explaining the mass and radius of neutron star as heavy as twice the solar mass.
