New variable stars in field SA9
Listed in IVOA Registry (Virtual Observatory)
The 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.
Description
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.
