Light time effect in the system V2294 Cyg.

LISKA J.

Abstract (from CDS):

Light Time Effect with an eight year period is proposed for the overcontact binary system V2294 Cyg as an explanation for variations in its O–C diagram. Preliminary parameters of three-body system were determined. The published orbital period of about 3 years of a third body as well as the other parameters, based on Kepler photometry, for the possible triple system V2294 Cyg (Conroy et al. 2014), were found to be less reliable.
