从爱因斯坦对9个大陵五类系统的巡天中观测到的X射线光度与Pallavicini等人（1981）对单个或相距甚远的快速旋转晚星的观测结果相似，但比具有相似轨道周期和光谱类型的RS CVn星的观测结果低一个数量级。它的结论是，X射线发射是最有可能与周围的次级热日冕。低光度的大陵五系统相对于RS CVn系统被认为是可能的解释。之前在星星上公布为N83-22074
The observed X-ray luminosities seen from an Einstein survey of nine Algol like systems are similar to those found by Pallavicini, et al. (1981) for single or widely separated rapidly rotating late stars, but fall an order of magnitude below those seen from RS CVn stars with similar orbital periods and spectral types. It is concluded that the X-ray emission is most probably associated with a hot coronae surrounding the secondary. Possible explanations for the lower luminosity of the Algol systems relative to the RS CVn systems are considered. Previously announced in STAR as N83-22074
