V649-CASSIOPEIAE - A MULTIPLE STAR SYSTEM

Previously published light and radial-velocity curves of the eclipsing and spectroscopic binary V649 Cassiopeiae are reexamined using the Wilson-Devinney program. Two solutions are presented, both leading to typical B-type masses and radii for the two components. One of the solutions calls for large amounts of third light (42% of the total light in V, 46% in B). We speculate about the possible nature of this source of third light, and we plead for new photometric and spectroscopic observations of this bright (V = 6.53) system.
