Abstract

Photoelectric observations of the eclipsing variable β Per, were obtained inUBV standard system, and new elements for the primary minimum were determined as

$$J.D. = 2445641.5135,O - C = 0_.^d 0.009.$$

The light curves of the system were analysed using Fourier techniques in the frequency-domain. The fractional radii of both components are

$$r_1 = 0.217 \pm 0.002,r_2 = 0.233 \pm 0.002andi = 85.5 \pm 0.5.$$

Absolute elements were derived and the effective temperatures are

$$T_1 = 11800K,T_2 = 5140K.$$
