AI 中文摘要
我们在有限温度下，利用SU(3)南布-乔拉-拉西尼奥（NJL）模型研究奇异夸克物质（SQM）与原夸克星（PQSs）的热力学性质，特别纳入轴子场与矢量相互作用的效应。结果表明，这些相互作用会显著影响原夸克星在演化线等熵阶段的物态方程（EoS）、组分夸克质量、熵密度及最大质量。此外，我们揭示了早期演化中存在独特的热力学特征：与无中微子情况相比，被俘获中微子的存在会使电子数密度大幅增加，同时抑制核心温度。这些发现凸显了轴子效应、味依赖矢量相互作用及粒子组分在确定有限温度下致密星可观测性质中的关键作用。
英文摘要
We investigate the thermodynamical properties of strange quark matter (SQM) and proto-quark stars (PQSs) within the SU(3) Nambu-Jona-Lasinio (NJL) model at finite temperature, specifically incorporating the effects of axion fields and vector interactions. Our results demonstrate that these interactions significantly influence the equation of state (EoS), constituent quark masses, entropy density, and the maximum star mass of PQSs at the isentropic stages along the star evolution line. Furthermore, we reveal a distinct thermodynamic signature in the early evolution: the presence of trapped neutrinos leads to a substantial increase in electron number density while simultaneously suppressing the core temperature compared to the neutrino-free case. These findings may highlight the crucial role of the axion effects, flavor-dependent vector interactions, and particle composition in determining the observable properties of compact stars at finite temperature.
