论文摘要
最新的Gaia Data Release 3提供了一个机会，可以扩大带有经典CEPHEID变量的银河开放式群集的普查，从而加强了宇宙距离。全面的分析得出了与45个开放群体相关的50个经典的头孢菌，其中39个开放式群集经典的头孢菌对被认为可能是可能的，其余的11对被认为是不可能的，但值得跟进。我们有两个先前由我们识别的群集可能是主机经典的头孢虫（OC-0125/V1788 CYG和OC-0675/OGEL-BLG-CEP-114）。此外，我们在银河磁盘中确定了38个新的开放群集候选。
The latest Gaia Data Release 3 provides an opportunity to expand the census of Galactic open clusters harboring classical Cepheid variables, thereby bolstering the cosmic distance scale. A comprehensive analysis yielded a total of 50 classical Cepheids associated with 45 open clusters, of which 39 open cluster-classical Cepheid pairs are considered probable, with the remaining 11 pairs considered improbable but worth following up. Two previously identified clusters by us possibly host classical Cepheids (OC-0125/V1788 Cyg and OC-0675/OGLE-BLG-CEP-114). In addition, we identify 38 new open cluster candidates within the Galactic disk.
