Scientific paper

Photoelectric observations of the eclipsing variable β Per, were obtained in UBV standard system, and new elements for the primary minimum were determined as J.D. = 2445641.5135, O-C = 0d.0.009. The light curves of the system were analysed using Fourier techniques in the frequency-domain. The fractional radii of both components are r1 = 0.217±0.002, r2 = 0.233±0.002 and i = 85.5±0.5. Absolute elements were derived and the effective temperatures are T1 = 11800K, T2 = 5140K.
