Spectroscopic orbit of CC Comae.
Abstract
Radial velocity measurements of CC Corn, the shortest period W UMa-type system, are resented. The results are combined with photometric results to provide an estimate of the absolute elements. The system has total luminosity 0.29 :1: 0.03 Lu and masses of 0.69 :1: 0.06 , and 0.36 :1: 0.03 @. Formal errors are quoted here, and the possibility of much larger systematic errors is discussed in the text. The value of the mass ratio derived spectroscopically (0.52 :1: 0.03) conflrrns the value derived from photometry. The distance to CC Corn (83 :1: 4 pc) is discussed with reference to membership of the Coma cluster (Mel 111). The importance of CC Corn for theoretical models of contact binary systems is stressed. Key words: stars: individual-spectroscopic elements-contact binaries
