标题： Slow Stable Self-bound Hybrid Star Can Relieve All Tensions

摘要： 一些最近的脉冲星观测无法自然地融入中子星的传统图像：与HESS J1731-347和XTE J1814-338相关的致密天体在低质量范围内半径太小，而GW190814的次级成分质量太大，无法与GW170817事件的约束相兼容。 在本研究中，我们证明了所有这些异常观测和矛盾，以及其他的传统观测，如PSR J0740+6620、J0030+0451和PSR J0437-4715的最新NICER观测结果，可以通过一种新的广义混合星类型自然地同时解释，这种混合星在缓慢相变背景下是自束缚且径向稳定的，并且某些子集甚至在快速相变背景下也可以实现。 作为概念验证，我们使用混合夸克星、倒置混合星和混合奇异星作为基准示例，明确展示了在缓解与致密星的质量、半径和潮汐可变形性相关的所有矛盾方面，缓慢稳定自束缚混合星的优势和可行性。 显示英文摘要

摘要： Some recent pulsar observations cannot naturally fit into the conventional picture of neutron stars: the compact objects associated with HESS J1731-347 and XTE J1814-338 have too small radii at the low-mass regime, while the secondary component of GW190814 is too massive for neutron stars to be compatible with constraints from the GW170817 event. In this study, we demonstrate that all these anomalous observations and tensions, together with other conventional ones such as recent NICER observations of PSR J0740+6620, J0030+0451, and PSR J0437-4715, can be naturally explained simultaneously by a new general type of hybrid stars that are self-bound and radially stable in the slow phase transition context, and by some subsets even in the rapid phase transition context also. As a proof of concept, we use hybrid quark stars, inverted hybrid stars, and hybrid strangeon stars as benchmark examples to explicitly demonstrate the advantage and feasibility of slow stable self-bound hybrid stars in relieving all tensions related to compact stars' masses, radii, and tidal deformabilities.
