Abstract

The results of three-color photometry of eleven RW Aur type stars, based on the numerous observations obtained during 1960—64 are given here. The stars studied are: RW Aur, RY Tau. BP Tau, Vm Ori. HK Ori, CO Ori, GW Ori. MH 265-3, SV Cep. BH Cep and BO Cep. Some of them which belong to the early spectral classes are characterized by light variations similar to Algol type stars, though at the same time they differ from each other. On the (U, V) and (V, U-V) diagrams drawn for the RW Aur (fig. 13 and 14) one can notice the influence of the second component when the star becomes fainter than V=ll.0. For CO Ori almost all the deep minima and maxima prove to be double. The Hertzsprung-Russell diagram for 6 stars has been drawn. As it is seen and as it was expected the stars under consideration fall above the line of the two-color diagram at the moments of their maxima. RW Aur itself and BP Tau do not follow this regularity. For RW Aur this may be partially explained by its being a double star.
