Scientific paper

In this paper we parameterize the photoelectric waves in the light curves of BH Vir in B and λ 5125Å bands by Hoffmann (1982) by using the Wilson-Devinney program. The principal results are as follows: (1) Themass ratio obtained from the photoelectric light curves is q =m2/m1 = 0.967. (2) The photosphere temperature of the primary is T1 = 5947 K. (3) The distortion waves in the light curves can be fitted satisfactorily with the spot model of two hot spot activities on the primary star.
