... We present a computer program for modelling energy flux distribution and light curves of eclipsing binaries from far ultraviolet to infrared regions. The Roche model is assumed. Proximity effects of components (reflection of radiation and surface gravity darkening) are taken into account. ... Figure 1: The surface temperature distribution for Algol A-B system before (upper plot) and after (lower plot) correction for temperature due to the irradiation effect. ...

... 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. ...
