论文摘要
我们银河系中的很大一部分X射线源是低质量X射线二进制文件,其中包含一个黑洞或从重力绑定的低质量($ \ leq $ 1 m $ $ _ \ odot $)的同伴之星中积聚的中子星。这些系统是星系中恒星和积聚系统的老年人,通常具有较长的积聚历史。低质量X射线二进制文件根据其观察到的特性,例如X射线变异性和亮度,伴随星和/或紧凑对象的性质以及二进制配置,将其分为各种子类。在本章中,我们回顾了这些系统的子类现象学,并总结了有关其特征,人群及其在银河系中的分布的观察发现。
A large fraction of X-ray sources in our Galaxy are low-mass X-ray binaries, containing a black hole or a neutron star accreting from a gravitationally bound low-mass ($\leq$1 M$_\odot$) companion star. These systems are among the older population of stars and accreting systems in the Galaxy, and typically have long accretion histories. Low-mass X-ray binaries are categorized into various sub-classes based on their observed properties such as X-ray variability and brightness, nature of the companion star and/or the compact object, and binary configuration. In this Chapter, we review the phenomenology of sub-classes of these systems and summarize observational finding regarding their characteristics, populations, and their distribution in the Galaxy.
