论文摘要
最近对Ligo/Wirgo和Bieser的检测对中子星的特性施加了强大的限制。在这项工作中，我们研究了将它们建模为杂种恒星的中子星，这些恒星将其与夸克物质核心的紧凑物体围绕，周围是辐射物质的层。此外，我们考虑存在强烈的磁场，例如磁铁检测，例如最近发现的Swift J1818.0-1607。我们将组成粒子的异常磁矩的影响融合到密集物质状态的方程中，并分析不同的强子夸克相转变对这些紧凑型物体的动态稳定性的含义。这项研究表明，在我们模型的框架内可以满足质量，半径和潮汐变形性的限制，这可以满足大量脉冲星和重力波的观察。
The most recent detections of LIGO/Virgo and NICER have placed strong constraints on neutron stars' properties. In this work, we study neutron stars modeling them as hybrid stars, compact objects with a quark matter core surrounded by layers of hadronic matter. In addition, we consider the presence of strong magnetic fields, motivated by magnetars detection, like the recently discovered Swift J1818.0-1607. We incorporate the effects of the anomalous magnetic moment of the constituent particles into the equation of state of dense matter and analyze the implications of different hadron-quark phase transitions on the dynamic stability of these compact objects. This study shows that the constraints on the mass, radius, and tidal deformability, imposed by observations of massive pulsars and gravitational waves can be satisfied within the framework of our model.
