Cos-B X-Ray Observations of CYGNUS-X-3 - an Indications for Apsidal Motion
Abstract
Results are presented of three ∼40 d COS-B X-ray observations of Cyg X-3. The shape of the 4.8 h light curve showed variations on all observational time scales. An ∼20 d periodicity was found in the arrival time of the minimum of the light curve, interpreted as apsidal motion of an orbit with an eccentricity of ∼0.03.
