论文摘要
我们提出了一种新的紧凑型恒星的新恒星结构，即``跨星''，它由har子物质核心和夸克物质组成，与传统的杂化恒星相比具有倒置结构。这种独特的恒星结构自然而然地从夸克物质上引起了与化学物质交叉相关的奇异物质，在夸张的态度上，在夸张的情况下，在夸张的情况下，是在夸张的情况下，在夸张的情况下进行了过渡，这是夸张的事物。压力。我们发现，跨星的悬式物质和夸克物质组成之间的相互作用可以帮助解决Ligo/Wirgo GW170817所指示的小半径约束，这是针对最新的X射线观察到最新的PS ps-ps-ass-servive for the Mass pss的较大的恒星。种族和夸克物质的状态方程。
We propose a new stellar structure of compact stars, the ``cross stars" that consist of a hadronic matter core and a quark matter crust, with an inverted structure compared to the conventional hybrid stars. This distinct stellar structure naturally arises from the quark matter to hadronic matter transition associated with the chemical potential crossing, in the context of the quark matter hypothesis that either strange or up-down quark matter is the ground state of baryonic matter at low pressure. We find that the interplay between the hadronic matter and quark matter compositions of cross stars can help to reconcile the small radii constraints indicated by the LIGO/Virgo GW170817 event, the large radii constraints set for massive compact stars by recent NICER X-ray observations, and the recent observation of the most-massive pulsar PSR J0952-0607. This leaves more space open for the equation of states of both hadronic matter and quark matter.
