DALLAPORTA S., TOMOV T., ZWITTER T. and MUNARI U.

Abstract (from CDS):

GK Dra has been discovered by the Hipparcos mission as a 17 days eclipsing binary. We present here the first ground-based study of this star, based on extensive BV photoelectric photometry. We found a period of 9.974 days, equal depth primary and secondary eclipse (Deltam=0.35 mag), no color variation in eclipse, and one of the components being a delta Sct star with an amplitude of 0.04 mag and a period of about 2.7 hours.
