论文摘要
通过首次通过重力波和光GW170817观察二元中子星的合并，紧凑型二元合并现在已经成为核天体物理学的中心阶段。人们认为它们是R-Process元素生产的主要天体物理部位之一，并合并观察已成为限制物质特性的基本工具。在这里，我们尤其是在中子恒星合并的动力学方面，尤其是GW170817的当前理解。我们讨论了管理Inspral，Anserger和Postmerger Evolution的物理过程，并强调了这些过程，动力学和多通用器可观察到的连接。最后，我们讨论了该领域中的开放问题和问题，以及通过更好的理论模型和新观察的结合来解决这些问题。
With the first observation of a binary neutron star merger through gravitational waves and light GW170817, compact binary mergers have now taken the center stage in nuclear astrophysics. They are thought to be one of the main astrophysical sites of production of r-process elements, and merger observations have become a fundamental tool to constrain the properties of matter. Here, we review our current understanding of the dynamics of neutron star mergers, in general, and of GW170817 in particular. We discuss the physical processes governing the inspiral, merger, and postmerger evolution, and we highlight the connections between these processes, the dynamics, and the multimessenger observables. Finally, we discuss open questions and issues in the field and the need to address them through a combination of better theoretical models and new observations.
