Light curves and elements of AR Draconis.
Abstract
B and V light curves of the eclipsing system AR Dra were obtained during the years 1976 and 1977. A small seasonal change in the light curves can be seen. Ten new epochs of minimum and an improved value for the period are derived. The seasonal light curves were analysed using a similar-ellipsoid model and assuming a Roche geometry. Key words: eclipsing binaries - photometry
