The most convincing evidence of black holes comes from research into binary star systems 黑洞最强有力的证据来自对双星系的研究。
In some binary star systems, gas escapes from one star and is captured by the gravity of the other to form a disk 某些双星系统中,当从一个恒星逃出的气体被另一个星体的重力捕获时,也会形成盘状结构。
Many stars orbit around other stars under the mutual gravitational attractions . if two stars orbit around one another, they form a binary star system 在天空中,不少恒星会在相互的引力下互相绕著对方运行,假若系统只有两颗星,我们会称之为
But there are images of binary star systems consisting of one normal star and one black hole, and of the central regions of galaxies that are believed to contain black holes 但是有由一个黑洞和一个正常恒星组成的双子星系统的图像,和被认为包含有黑洞的星系中心区域的图像。
Analysis of the x-ray data shows that the point sources are associated with binary star systems that contain a neutron star or black hole that is pulling matter away from a normal star 对x射线数据的分析表明,点源与包含有中子星或黑洞(它们正从正常恒星吸走物质)的双星系统成协。
Sometimes, in a binary star system, one star will pass in front of the other producing what we call eclipsing binary . it can be treated as a special kind of visual binary . eclipsing binary systems are variable stars see below :有些双星系统,其中一颗星会在另一颗星前经过,产生周期性的光度变化,我们称这种双星为食双星,基本上我们可以把食双星看成为目视双星的一种。
These events include two kinds of stellar explosions : ( 1 ) nova explosions, in which one of the two members of a binary star system hurls dust and gas into space; ( 2 ) much more violent supernova explosions, in which a star collapses, then throws off most of its matter 这些事件包括两种类型的恒星爆发:(1)新星爆发,双星系统中的一员将气体和尘埃猛烈抛入太空;(2)更为猛烈的超新星爆发,那是一颗恒星崩溃时几乎把它所有物质都抛出去了。
