| Abstract: | We report the results of the first-ever CCD spectroscopic observations of the eclipsing variable CCCas with massive early-type components. The measured semi-amplitudes of the radial velocity curves of the components, K 1 = 123.9 km/s and K 2 = 292.4 km/s, are comparable with the published data, and the center-of-mass velocity of the system was found to be V 0 = ?20.4 km/s, which is about ?10 km/s greater than the earlier published results. This fact may support the published hypothesis about the presence of a third body in the system. |
