| Abstract: | Using WOOD's (1972) model we have analyzed two sets of photoelectric observations as yet unsolved, i.e., ROVITHIS ' and ROVITHIS -LIVANIOU's (1980) B and V light curves of the semi-detached system u Her and BROGLIA's (1961) three-colour observation of the detached system UV Leo. The observations of u Her have yielded solutions in which the secondary's radius exceeds its ROCHE lobe. On the other hand, our new elements of UV Leo confirm the most recent investigations, thus giving for the primary eclipse an unexpected occulatation solution which hardly permits a simple picture of UV Leo. |
