cds-question@unistra.frvariable-starsphotometryThe new stage of work on digitizing the astronomical plates of the Sternberg Astronomical Institute's collection and searching for new variable stars using the digitized photographic plates includes a considerable improvement of the automated search techniques for objects with variable brightnesses. In particular, the technique for taking into account the non-linear response of the photographic light detector has been improved. Applying the improved techniques to 182 digitized images of a 10{deg}x10{deg} field centered at SA9, obtained from scanning photographic plates taken with the Sternberg Astronomical Institute 40-cm astrograph, has enabled the discover and study of 77 new variable stars (MDV 519-595). These include 3 Cepheids, 2 probableBY Draconis stars, 65 eclipsing binaries, 3RR Lyrae stars, 1 high-amplitude {delta} Scuti star (HADS), and 3 irregular variables. Special CCD observations have confirmed the presence of brightness variations in 7 of the 77 variables that were initially considered uncertain.2014AZh....91..382Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/91/382CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AZh/87/1087 : New variable stars in 66 Oph field (Kolesnikova+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/91/382https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/91/382http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/91/382https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/91/382https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/91/382http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/91/382GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AZh/91/382/table1 (New variable stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/91/382/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/91/382/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/91/382/table1?GETtext/xml+votable180.050000true38.578208363.21194440.0055555555555555565/819 820 830 6/3186 3190 3199 3229 3267 3268 3273 3274 3275 3285 3286 3289 3293 3294 3295 3296 3299 3301 3303 3309 3313 3314 3315 3316 3317 3318 3368 3370 3456 3459 3467 3653 3664https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/91/382?format=asciiOpticaldefaultJ/AZh/91/382/table1New variable starsrecnoRecord number assigned by the VizieR team.
