Anomalous period change of UX Ursae Majoris in 1977.
Abstract
The times of 32 primary minima of the eclipsing binary and nova-like variable UX UMa were measured over 1976 and 1977 using higb-speed photometry. The corresponding (0- C)s for 1977 depart significantly from the periodic curve proposed by Mandel. Key worjs: nova4ike variables-eclipsing binaries
