S10947 Aquilae = RX J2009.8+1557: a probable RS CVn star which sometimes stops its eclipses.

RICHTER G.A. and GREINER J.

Abstract (from CDS):

We report the discovery of a new variable star, called S10947 Aql, as the likely optical counterpart of RX J2009.8+1557. The optical variability pattern as well as the detected X-ray emission suggest that it is a chromospherically active binary of the RS Canum Venaticorum (= RS CVn) type. We discovered an occasional disappearance of the eclipsing minima as well as large variations in the eclipse amplitude. We discuss possible causes of this peculiarity.
