DK And: Neuklassifizierung als EW Bedeckungsveraenderlicher mittels CCD Beobachtungen.
HAMBSCH F.-J. and HUSAR D.
Abstract (from CDS):
This paper describes the reclassification of DK And, formerly classified as RRc type star, as EW binary. 1599 CCD unfiltered and filtered (V and R band) observations between 1999 and 2005 show, that the star is actually an eclipsing binary star with a period of P = 0.4892224 ± 0.0000002 d with epoch E0 = 2451435.4353 ± 0.0010 (if all historic data were taken into account). From our new observations 12 timings of minimum light are given.
