A Analysis of the Light and Radial Velocity Curves of do CAS
DO Cas is a short period (P=0.68day) eclipsing binary star and is classified as a near-contact binary by Shaw (1990). There is no published radial velocity curve for this short period binary after Mannino (1958). Hill (1991) suspected that Mannino's radial velocity curve had some serious mistak...
