Abstract

The Vand B light curves of the eclipsing binary RU Eridani, published by Sarma and Sanwal (1981), have been analysed by means of the Wilson and Devinney (1971) method, in order to obtain a solution based on the Roche model, as distinct from the Russell and Merrill model, used by Sarma and Sanwal. The system turns out to consist of an evolved Kl secondary which appears to fili the lobe, capable of containing its mass, and of an FO V primary, which seems almost to fili its own. An estimate of the absolute elements of RU Eri has been made, on the assumption that the primary has a mass corresponding to its spectral type according to Allen (1973).
