New periods of variable stars in Cygnus based on a quarter of century of photographic observations
Abstract
This work summarizes the results of photographic photometry obtained over 24 years at the Skalnaté Pleso (1979-1993) and Asiago (1969-1988) observatories. The period of light changes, the epoch of the maximum or of the minimum, the type of variability and, in some cases, possible causes of the long-term behaviour of light changes were determined for 17 variable stars. Tables 2 is only and Table 3 also available at the CDS via anonymous ftp 130.79.128.5 and http://cdsweb.u-strasbg.fr/Abstract.html
