论文摘要
中子星（NS）合并为我们提供了使用多通信的天体物理观测值富含物理学的信息。这种合并的可能残留物之一是差异旋转的热质量中子星。合并残留物的稳定性至关重要取决于状态（EOS）的基本方程，因此提供了一种探测NSS密集物质性质的方法。在这项工作中，我们在NS内部寻找合并残留物的世俗稳定性中包含物质的陌生签名。我们还使用最近提出的方法来粗略地估计合并残留物的崩溃时间和合并迅速倒入黑洞的阈值质量。
Neutron star (NS) mergers provide us with information rich in physics using multi-messenger astrophysical observations. One of the probable remnants of such a merger is a differentially rotating hot hypermassive neutron star. The stability of the merger remnant depends crucially on the underlying Equation of State (EoS) and thus provides a method to probe the nature of dense matter in NSs. In this work, we search for possible signatures of strangeness containing matter in the NS interior on the secular stability of the merger remnant. We also use recently proposed methods to make a rough estimate the collapse time of the merger remnant and the threshold mass above which the merger promptly collapses to a black hole.
