Possible large intrinsic variability in the short period eclipsing binary RS Scuti.

COOK S.P.

Abstract (from CDS):

An intrinsic variation in the Beta Lyrae type eclipsing binary RS Scuti is indicated, based on 82 visual estimates. Comparison of primary eclipse (composite) light curves obtained in 1984 and 1992 show this star 0.5 magnitude fainter in 1992. Critical re-examination of published magnitude ranges also suggests an intrinsic variation. As to its cause, starspot activity and the presence of a third body are considered. An O-C plot for 1909 - 1992 is analyzed, new ephemeris elements are derived, and no evidence of a third body is found.
