数字化莫斯科收藏盘上的新变星。Field 66 Ophiuchi（北半部）
New Variable Stars on Digitized Moscow Collection Plates. Field 66 Ophiuchi (Northern Half)
摘要：
我们开始使用平板扫描仪对莫斯科收集的天文底片进行数字化。应用了数字图像的照相测光技术，从而能够有效地搜寻新的变星。我们在1976--1995年用斯滕伯格研究所40厘米天体照相机拍摄的以66 Oph为中心的10 × 5度北半球的14万颗恒星中寻找新变星，得到274颗新发现，其中：2颗可能的第二星族造父变星，81颗食变星，5颗高振幅的盾牌座δ星（HADS），82颗天琴座RR星，81颗食变星，12颗食变星。62颗红色不规则变星和41颗红色半规则变星; 1颗缓慢的不规则变星颜色不是红色。测定了周期变星的轻元素。在后续的CCD观测中，我们探测到了30颗疑似变星，确认了新的疑似变星表中的11颗恒星，并对已列入变星总表的2颗恒星推导出了新的轻元素。
英文摘要：
We initiated digitization of the Moscow collection of astronomical plates using flatbed scanners. Techniques of photographic photometry of the digital images were applied, enabling an effective search for new variable stars. Our search for new variables among 140000 stars in the 10 x 5 degrees northern half of the field centered at 66 Oph, photographed with the Sternberg Institute's 40-cm astrograph in 1976--1995, gave 274 new discoveries, among them: 2 probable Population II Cepheids; 81 eclipsing variables; 5 high-amplitude Delta Scuti stars (HADSs); 82 RR Lyr stars; 62 red irregular variables and 41 red semiregular stars; 1 slow irregular variable not red in color. Light elements were determined for periodic variable stars. We detected about 30 variability suspects for follow-up CCD observations, confirmed 11 stars from the New Catalogue of Suspected Variable Stars, and derived new light elements for 2 stars already contained in the General Catalogue of Variable Stars.
