Abstract

Abstract New two-colour observations of AH Tau in 1986 are given. The light curves changed appreciably since 1973, the new curves are symmetrical. A photometric solution is obtained using the Wilson-Devinney method. It has a degree of overcontact of 9.1%. The two components are found to be unevolved. The absolute dimensions are found with the help of the Dworak's photometric parallax. Its distance being twice that of the Pleiades, it is probably not a member of the Pleiades cluster.
