第一次探测到引力波从一个双中子星星合并（GW 170817）和伴随的电磁辐射，令人印象深刻地推进了我们的合并过程的理解，并设置了一些第一个约束的宏观性质的中子星，与高密度状态方程的直接影响。我们讨论了有关中子星星合并的工作，重点是合并后的引力波发射。这些研究是基于合并的数值模拟和调查的候选状态方程的中子星星物质的大样本。其目标是将可观测量与潜在的物理问题联系起来。这提供了一种通过确定中子星星半径来限制高密度物质性质的方法，正如将合并后阶段的主导引力波频率峰值与一定质量的非旋转中子星半径联系起来的经验关系所推断的那样。我们澄清了次级峰的物理起源，并根据其相对强度讨论了光谱分类方案。本文还讨论了主峰和次峰的观测前景。黑洞坍缩的临界质量与非旋转中子星的最大质量和致密性有另一个经验关系，这个关系可以半解析地推导出来。然后，对GW 170817的观测为典型质量的中子星设定了一个绝对最小半径，这仅仅是基于最少数量的假设。我们讨论了未来的前景，根据目前的引力波探测器的计划升级。
The first detection of gravitational waves from a binary neutron star merger (GW170817) and the accompanying electromagnetic emission has impressively advanced our understanding of the merger process and has set some first constraints on the macroscopic properties of neutron stars, with direct implications for the high-density equation of state. We discuss work on neutron star mergers focusing on the postmerger gravitational-wave emission. These studies are based on numerical simulations of the merger and survey a large sample of candidate equations of state for neutron star matter. The goal is to connect observables with the underlying physics questions. This offers a way to constrain the properties of high-density matter through the determination of neutron star radii, as inferred by an empirical relation connecting the dominant gravitational wave frequency peak in the postmerger phase to the radius of nonrotating neutron stars of a certain mass. We clarify the physical origin of secondary peaks and discuss a spectral classification scheme, based on their relative strength. Observational prospects for the dominant and the secondary peaks are also discussed. The threshold mass to black hole collapse is connected by another empirical relation to the maximum mass and compactness of nonrotating neutron stars, which can be derived semi-analytically. The observation of GW170817 then sets an absolute minimum radius for neutron stars of typical masses, based only on a minimal number of assumptions. We discuss future prospects, in light of the planned upgrades of the current gravitational wave detectors.
