英国皇家天文学会月报（Monthly Notices of the Royal Astronomical Society）周三指出，科学家于2017年8月首次观察到中子星碰撞会产生重力波、光与黄金、铂金、银等多种超重元素后，将它称为“Kilanova”，近期科学家终于研究出中子星爆炸为何会有重金属的过程和原因。

科学家表示，他们把2016年8月观察到的“GRB160821B”伽玛射线爆炸纪录拿出来和“Kilanova”对照发现，两者同样是在融合的过程中产生引力波，并伴随著短而弱的伽玛射线爆炸，此外，“GRB160821B”在爆炸之后，瞬间创造了数百个小行星大小的黄金和白金，这也间接证实了“Kilanova”为何能产生大量重金属。

据马里兰大学天文学家特洛仄博士指出，“Kilanova”可能来自黑洞和中子星的融合，但目前对于爆炸事件是否会影响X射线，红外线，无线电和光学观测中产生不同的成果，还有待研究。

同样来自马里兰大学的杰弗里瑞安博士也表示，这些超重元素可能来自于一颗拥有超强磁力且超大质量的中子星，通常都称它为“磁星”，但按理论来看，每颗中子星应该都会减缓甚至停止重金属的产生，最新研究分析却显示，这些超重元素重能以某种方式逃脱剩余残物的淬火影响，进而变成重金属。
