AI 中文摘要
近期对HESS J1731--347超新星遗迹中致密中心天体（CCO）的分析显示，其存在质量低、半径小的异常组合，而热辐射则表明在其估算年龄下表面温度相对较高。在统一理论框架内协调这些结构与热学性质，可为致密物质的物态方程和组成提供重要约束。本研究探究带负电K介子凝聚的热学效应，该奇异相会软化物态方程，有助于重现HESS J1731--347的推断整体性质。我们发现K介子凝聚的发生会大幅加速热演化，导致表面温度远低于观测推断范围。在采用的冷却框架内，K介子凝聚无法同时解释HESS J1731--347的结构与热学性质。
英文摘要
Recent analyses of the central compact object in the HESS J1731--347 supernova remnant suggest an unusual combination of a low mass and small radius, while its thermal emission indicates a relatively high surface temperature at its estimated age. Reconciling these structural and thermal properties within a unified theoretical framework may provide important constraints on the equation of state and composition of dense matter. In this work, we investigate the thermal consequences of negatively charged kaon condensation, an exotic phase that softens the equation of state and facilitate the reproduction of the inferred bulk properties of HESS J1731--347. We find that the onset of kaon condensation strongly accelerates the thermal evolution, leading to surface temperature substantially below the observationally inferred range. Within the adopted cooling framework, kaon condensation therefore cannot simultaneously account for the structural and thermal properties of HESS J1731--347.
