标题： Contact Binary Variables as X-ray Sources

摘要： 我们展示了存档的X射线点源与在全天自动星象巡天（ASAS）中发现的W UMa变星之间的交叉认证。在ASAS的300平方度巡天区域中，发现36颗W UMa恒星与X射线辐射有关联。我们计算了这些W UMa系统的距离以及它们的X射线光度。我们的数据支持这些快速自转恒星中观察到的“超饱和”现象，即W UMa恒星旋转得越快，其X射线光度就越弱。 显示英文摘要

摘要： We present cross-identification of archived X-ray point sources with W UMa variable stars found in the All-Sky Automated Survey (ASAS). In a surveyed sky area of 300 square degrees of ASAS, 36 W UMa stars have been found associated with X-ray emission. We compute the distances of these W UMa systems and hence their X-ray luminosities. Our data support the "supersaturation" phenomenon seen in these fast rotators, namely that the faster a W UMa star rotates, the weaker its X-ray luminosity.
