The eclipsing binary U Cephei - new observations and solutions

Observations of the interacting eclipsing binary system U Cephei in the standard UBV system were obtained at the Rosemary Hill Observatory of the University of Florida during the most recent period of activity (1974 October until 1976 May). Double coverage of more than 95 per cent of the light curve was obtained. Since analysis of the irregularities in the light curve depends greatly on an accurate geometrical model, three solutions by different techniques were attempted. The D. B. Wood solution failed, since asynchronous rotation of the primary star is not included in the model. Reasonable agreement between the Russell–Merrill and Wilson–Devinney solutions was achieved.
