利用光-红外约化自行图对Luyten星进行分类

Classifying Luyten Stars Using An Optical-Infrared Reduced Proper Motion Diagram

Samir Salim, Andrew Gould

摘要:

我们提出了一个V-J约化自行(RPM)图的恒星在新Luyten十分之二(NLTT)目录。与基于原始NLTT数据的RPM图形成鲜明对比的是,这张光学-红外RPM图显示了白矮星、次矮星和主序星的不同轨迹。因此,它允许识别白矮星和亚矮星候选者,这些候选者有很高的可能性是真实的。

英文摘要:

We present a V-J reduced proper motion (RPM) diagram for stars in the New Luyten Two-Tenths (NLTT) catalog. In sharp contrast to the RPM diagram based on the original NLTT data, this optical-infrared RPM diagram shows distinct tracks for white dwarfs, subdwarfs, and main-sequence stars. It thereby permits the identification of white-dwarf and subdwarf candidates that have a high probability of being genuine.
