论文摘要
我们报告了对OGLE GALAXY变异性调查的光学对象对位的CepheID变量恒星进行全面搜索的结果。我们识别出第一个发行版的ogle cepheids cepheids的第一个发行版中未包含的742个头，并重新分类了几十个先前发表的变量。升级的系列包括1974年的古典，1625型II型和119个异常头，位于约3000平方工的区域，覆盖了银河系的磁盘和凸起。 We present the most interesting objects in our sample: an isolated group of long-period doublemode classical Cepheids pulsating in the fundamental mode and first overtone, the first known Galactic double-mode Cepheid with the second and third overtone excited, double-mode type II Cepheids, candidates for single-mode first-overtone BL Her stars, and Cepheids showing simultaneous eclipsing variability.我们还讨论了II型和异常的头孢菌素，它们是球状簇的潜在成员。
We report on the results of a comprehensive search for Cepheid variable stars in the fields photometricallymonitored by the OGLE Galaxy Variability Survey. We identify 742 Cepheids not included in the first release of the OGLE Collection of Galactic Cepheids and reclassify several dozen previously published variables. The upgraded collection comprises 1974 classical, 1625 type II, and 119 anomalous Cepheids located in the area of about 3000 square degrees covering the disk and bulge of the Milky Way. We present the most interesting objects in our sample: an isolated group of long-period doublemode classical Cepheids pulsating in the fundamental mode and first overtone, the first known Galactic double-mode Cepheid with the second and third overtone excited, double-mode type II Cepheids, candidates for single-mode first-overtone BL Her stars, and Cepheids showing simultaneous eclipsing variability. We also discuss type II and anomalous Cepheids that are potential members of globular clusters.
