Scientific paper

New UBV photoelectric observations of EB-type contact binary DO Cas were made on four nights from February 1986 to February 1987. The obtained light curves in combination with the radial-velocity curve of the primary published by Mannino (1958) of DO Cas have been solved simultaneously using the Wilson-Devinney synthesis code. The system is found to be a contact binary with a degree of overcontact of 14 percent. It may be concluded that DO Cas is an evolved contact binary.
