论文摘要
开放恒星簇中的白矮人（WDS）是一个非常有用的恒星合奏。尽管许多研究人员使用开放群集WD来研究初始质量关系，但这一恒星样本还启用了许多其他进化研究，包括搜索随机质量损失，二进制恒星进化的研究以及金属性对WD形成和进化的影响的测量。但是，使用天体数据（例如适当的运动）从开放群集样本中删除污染的场WD，这一点至关重要。大多数开放群集WD都需要多上述地面成像。同样，必须考虑初始质量质量平面中的强相关误差。我们使用大型开放群集WD样品和蒙特卡洛技术说明了这种考虑的重要性。
White dwarfs (WDs) in open star clusters are a highly useful ensemble of stars. While numerous researchers use open cluster WDs to study the initial-final mass relation, numerous other evolutionary studies are also enabled by this sample of stars, including searches for stochastic mass loss, studies of binary star evolution, and measurements of metallicity impacts on WD formation and evolution. However, it is crucial to use astrometric data such as proper motions to remove contaminating field WDs from open cluster samples; multi-epoch ground based imaging is needed for most open cluster WDs. Also, the strongly correlated errors in the initial mass - final mass plane must be considered; we illustrate the importance of this consideration using a large open cluster WD sample and Monte Carlo techniques.
