LIGO-Virgo mystery object gap between neutro holes
2020/7/3
When the most massive stars die, they collapse under their own gravity and leave behind black holes. When stars that are a bit less massive die, they explode in supernovas and leave behind dense, dead...

NSF latest LIGO-Virgo binary black hole merger
2017/12/19
Scientists supported by the National Science Foundation (NSF) recently announced the detection of the merger of two relatively "light" black holes, 7 and 12 times the mass of the sun, respectively, at...
两个黑洞（中子星）在强大引力的相互作用下相互绕转着靠近彼此，越转越快，直至最后发生碰撞并合。在不断靠近彼此的过程中，就已经产生了引力波。理论预言，如果它们质量相当，在相互靠近的过程中，引力波的辐射不仅带走了能量，还能使得轨道从一个大椭圆较快地逐渐收缩到一个圆，到最后发出被LIGO探测到的高频强引力波信号时，轨道已经很圆了。
