标题： The binaries of the NS-NS merging events

摘要： 本文讨论了NS-NS（中子星-中子星）并合事件的一些问题，强调从NS（中子星）质量分布中收集的数据和独立证据表明，GW170817的前身是一个不对称系统。最大静态NS质量（可能出现在红背-黑寡妇系统中）的问题与该特定事件相关值存在矛盾。 显示英文摘要

摘要： We discuss in this contribution some issues of the NS-NS merging events, emphasizing that the data and independent evidence gathered from NS mass distribution suggest an asymmetric system as the progenitor of GW170817. The issue of the maximum static NS mass (likely found in redback-black widow systems) is in tension with the value related to this particular event.
