论文摘要
使用流体动力学模拟，用于大量的状态高密度物质方程（EOSS），我们系统地确定阈值质量m_thres，以迅速黑洞形成等于质量和非对称中子星（NS）合并。我们设计了迄今为止最直接，一般和准确的方法，以确定从合并观测值揭示M_THRE的非旋转NS的最大最大质量。考虑到具有强子夸克相变的混合EOSS，我们确定了NS合并中Quark Matter的新的，可观察到的签名。此外，我们的发现在重力波搜索，KilOnova解释和对NS性质的多门限制中有直接应用。
Using hydrodynamical simulations for a large set of high-density matter equations of state (EoSs) we systematically determine the threshold mass M_thres for prompt black-hole formation in equal-mass and asymmetric neutron star (NS) mergers. We devise the so far most direct, general and accurate method to determine the unknown maximum mass of nonrotating NSs from merger observations revealing M_thres. Considering hybrid EoSs with hadron-quark phase transition, we identify a new, observable signature of quark matter in NS mergers. Furthermore, our findings have direct applications in gravitational wave searches, kilonova interpretations and multi-messenger constraints on NS properties.
