WebOver half of the sources detected in the Extreme-Ultraviolet Explorer (EUVE) All-Sky Survey and Deep Survey (50-760 ?) that have known optical counterparts are late-type stars. The EUV emission from late-type stars is thought to originate from hot, collisionally dominated, optically thin plasmas, with temperatures ranging between 105 and 108 K, that are … Web海豚座HU，又稱Gliese 791.2，是一個位於海豚座的聯星系統，由兩顆紅矮星組成。 視星等為13.07 。 視差為113.4mas ，它距離太陽系約24.37光年（7.5秒差距）。. 海豚座HU是一顆聯星，週期明確，為538.6天。軌道是通過天體測量和光譜觀測得出的，儘管由於預計的旋轉速度很高，這很難做到。
