- Аннотация: Photoelectric U, B, and V observations of the polarized star AN UMa were made when the system was in two different states of mean optical brightness, and results are interpreted on the premise that the rate of accretion into the highly magnetized white dwarf is variable. The white and red dwarfs in the system have masses of about 1.0 and 0.25 solar mass, respectively, and the components are separated by about 6 x 10 to the 10th cm. Most optical emission comes from a hot spot located on the surface itself or in the accretion structure surrounding the white dwarf.
