Scientific paper

In this paper, observations of the eclipsing binary LX Per which were obtained in 1983 are presented. There is a wave-like distortion at outside eclipses with an amplitude ranging from 0.03 to 0.08 mag. The wave-like distortion was removed with a new approach. Then, the light curves were analyzed by the methods of Wood (1971) and Nelson, Davis, and Etzel (1982). The absolute parameters of the components were also calculated. The physical parameters of the components indicate that the cooler star has separated or has been departing from the Main Sequence.
