摘要

摘要 我们研究了九个疏散星团中由主序星(MS)和白矮星(WD)组成的未解析双星系统。这些系统位于色-星图上主序星的下方和左侧。我们比较了可能已经演化成白矮星的星团恒星数量和带有白矮星的未解双星系统候选者数量。位于主序以下的可能星团成员的数量一般少于预期的白矮星数量。紫外线观测比可见光观测更有把握地探测到白矮星和未解决的双WD+MS系统。

Unresolved Binary Systems with White Dwarfs in Open Star Clusters

We investigate unresolved binary systems with components of main sequence star (MS) and white dwarf (WD) in nine open clusters. These systems are located below and to the left of the main sequence on the color-magnitude diagram. We compare the number of cluster stars that have likely evolved into white dwarfs with the number of candidates for unresolved binary systems with WD. The number of probable cluster members lying below the main sequence, is generally less than the expected number of WDs. The observations in the ultraviolet could detect WDs and unresolved binary WD+MS systems more confidently than the observations in the visible range.
