... The RS CVn binary HD185510 consists of a K0 III giant which eclipses its faint blue companion every 21 days. The latter has been identified as an sdB star: it is the only such object known in a wide eclipsing binary and can only be observed in the ultraviolet, where its radial velocity amplitude and spectrum have been recorded. A detailed analysis of the orbit from a new ultraviolet light curve and previous radial velocities indicates a low mass (~0.3 solar masses) for the blue star. ...
