The variability of the Be stars

Abstract

Using the photometric and Be-star catalogues existing at La Plata, the photometric behavior of a sample of 140 Be stars has been studied over an average time interval of eleven years. As compared with a control sample of 100 normal B stars, about 50 % of the Be stars show variations in V and about 30 %, in B-V and U-B. These results confirm Feinstein’s conclusions (Z.f. Astroph. 68. 29 (1968)) based upon a smaller sample. The paper in full will be published elsewhere.
