More recently , dr . rosanne di stefano also from the harvard - smithsonian centre for astrophysics and i used the chandra x - ray observatory to detect objects dubbed " quasisoft " x - ray sources in nearby galaxies because of their low temperatures , which are at most four million degrees celsius . that is well below the temperatures expected for " hard " x - ray sources such as neutron stars or stellar mass black holes - which run between 10 million and 100 million degrees celsius - and still hotter than " soft " x - ray sources like white dwarfs
最近罗珊迪史提芬路博士她亦来自哈佛大学史密森天体物理中心和笔者利用钱德拉射线天文台在邻近星系侦测到一种奇怪的-射线源，我们称之为类软射线源，因为它们的温度最高只有摄氏400万度，远低于一般硬射线源，例如中子星和恒星型黑洞温度介乎摄氏1千万至1亿度，却又比软射线源例如白矮星为高。
