今日头条自媒体登陆科学家在银河系中发现一个违反常识的黑洞

A new black hole search method has just yielded fruit, and boy is it juicy. Astronomers have found a stellar-mass black hole clocking in at around 70 times the mass of the Sun - but according to current models of stellar evolution, its size is impossible, at least in the Milky Way.
一个新的搜寻黑洞的方法已经证明有效，而且收获颇丰。天文学家发现了一个黑洞，质量大约是太阳的70倍，但根据目前恒星演化的模型来看，至少在银河系中这种体积是不可能存在的。
The chemical composition of our galaxy's most massive stars suggests that they lose most of their mass at the end of their lives through explosions and powerful stellar winds, before the star's core collapses into a black hole.
银河系中最大的恒星的化学成分表明，在恒星的核心坍缩成黑洞之前，它们在生命的最后阶段会通过爆炸和猛烈的恒星风失去大部分质量。
The hefty stars in the mass range that could produce a black hole are expected to end their lives in what is called a pair-instability supernova that completely obliterates the stellar core. So astronomers are scratching their heads trying to figure out how the black hole - named LB-1 - got so chonky.
在能产生黑洞的质量范围内的超大恒星预计在毁灭之后会成为不稳定对超新星，头条号扩展链接，恒星的核心完全摧毁。所以天文学家也摸不着头脑，想弄清楚这个名为LB-1的黑洞为何如此巨大。
"Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," said astronomer Jifeng Liu of the National Astronomical Observatory of China.
中国国家天文台的天文学家刘继峰说：“根据目前大多数恒星演化的模型来看，这种质量的黑洞甚至都不应该存在于我们的星系中。”
"LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation."
“LB-1是我们想象中可能存在的质量的二倍，现在理论家们要想办法解释一下它是如何形成的。”
