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

    最近羅珊迪史提芬路博士她亦來自哈佛大學史密森天體物理中心和筆者利用錢德拉射線天文臺在鄰近星系偵測到一種奇怪的-射線源,我們稱之為類軟射線源,因為它們的溫度最高只有攝氏400萬度,遠低於一般硬射線源,例如中子星和恆星型黑洞溫度介乎攝氏1千萬至1億度,卻又比軟射線源例如白矮星為高。
