简介河内X射线双星及其光学对应体

A Brief Introduction to Galactic X-ray Binaries and Their Optical Counterparts

已被光学证认的约100个致密X射线源,绝大部分是一颗致密星(白矮星、中子星或黑洞)与另一恒星组成的双星。其中主要有三种类型:(1)伴星为大质量早型星,简称HMXB;(2)伴星为低质量晚型星,即LMXB;(3)激变变星。本文重点简介前两类的基本观测事实及理论模型,也顺便提到后者。

About 100 compact galactic X-ray sources have been identified optically. Most of them are binaries consisting of compact stars (white dwarfs, neutron stars or black holes). They can be divided into three main categories; (1) with a massive binary companion forming a High Mass X-ray Binary, or HMXB for simplicity, (2) with a low mass late type binary companion, or LMXB, (S) Cataclysmic variable. Here we give a brief introduction to them, putting less emphasis on the later.
