论文摘要

我们在本章中概述了中子星质量分布的问题,现有样本和新的重力波事件所推论的最大质量问题以及与地层事件的联系。结果表明,至少两个不同的质量量表(可能三个)受到贝叶斯和频繁分析的青睐,并且仅在经验理由上获得的最大质量是$ \ sim 2.5 m _ {\ odot} $,为GW190408 MERGER的较轻组件的解释提供了空间,可以通过gw190408 merger作为一个中子分析(效果分析)(效果由gw)进行了gw(效果分析)。我们讨论了一个僵硬的状态方程以及可用的超新星爆炸的状态(单元和二进制模拟)的理论构造和预期可在出生时提供群众的挑战。

We give in this Chapter an overview of the problem of neutron star mass distribution, the issue of the maximum mass as inferred from the existing sample and the new gravitational wave events, and the connection with the formation events. It is shown that at least two different mass-scales (and possibly three) are favored by Bayesian and frequentist analysis, and the resulting maximum mass on empirical grounds only is $\sim 2.5 M_{\odot}$, making room for an interpretation of the lighter component of the GW190408 merger as a neutron star (as suggested by the GW event population analysis). We discuss in some length the challenges for a theoretical construction of a stiff equation of state and the status of available supernova explosions (single and binary simulations) and AIC expected to provide the masses at birth.
