AI 中文摘要
本研究旨在寻找行星状星云（PNe）与疏散星团（OCs）的关联。在之前已知的约4800个银河系OCs中，目前仅有5个PNe。作为星团成员，PNe的性质可与它们的前身恒星相联系，这对一般的星系场PNe来说是不可能的。自盖亚天体测量卫星首次数据发布以来，已识别出数千个新的OC候选体，这为搜索已知PNe的宿主提供了新动力。统计上预计有30个OC - PN对。我们搜索了Hunt & Reffert（2023）发现的这些盖亚候选OCs，寻找已知的行星状星云中心恒星（CSPNe）作为PNe的实际代理且适用于自动搜索。我们在HASH数据库中识别出1个潜在的CSPN（IRAS 15127 - 5811），它被认为是假定星团HSC 2686的成员。另一个参数相似且角距离非常近的星团（Lynga 3）也可能是潜在宿主。我们将CSPN IRAS 15127 - 5811重新分类为带有双极星云的蓝超巨星。我们收集了这两个星团拟成员恒星的所有可用信息，得出结论：这两个所谓的星团都不真实。我们的结果对许多新识别出的恒星成员数量不多的OCs的真实性提出了很大质疑。
英文摘要
This study was motivated by the search for Planetary Nebulae (PNe) and Open Cluster (OCs) associations. Only 5 PNe are currently in Galactic OCs among the previous $\sim4,800$ OCs known. They are valuable because as cluster members their properties can be linked to their progenitor stars, something not possible for general field PNe. Since the GAIA astrometric satellite first data release, thousands of new OC candidates have been identified. This offers fresh motivation to search them as hosts for known PNe. Statistically we expect 30 OC-PN pairs to be present. We searched these GAIA candidate OCs, found by Hunt \& Reffert (2023), for known central stars of PNe (CSPNe) as a practical proxy for the PNe themselves and one suited to automated searches. We identified 1 potential CSPN (IRAS 15127-5811) of "Likely" PN [GKF2010] MN18 in the HASH database, as a claimed member of the putative cluster HSC~2686. A second cluster (Lynga~3) with similar parameters and in very close angular proximity could also be a potential host. Here we reclassify CSPN IRAS 15127-5811 as a blue supergiant with a surrounding bi-polar nebula. Nevertheless, we collected all available information on proposed member stars for both these clusters. We conclude that neither claimed cluster is real. Our results shed considerable doubt on the veracity of many newly identified OCs that have modest numbers of stellar members.
