Scientific paper

An efficient procedure for analyzing the variability of light curves of solar type eclipsing binaries has been implemented. By means of this procedure the UBV photoelectric light curves of ER Vul, observed in 1985, have been studied and three sinusoidal waves, which could explain both the short and the long time-scale variability, have been identified through the distortion of the light curves. A tentative interpretation is given to link these waves to the stellar activity.
