Observational study of the evolution of massive binary stars
Published online by Cambridge University Press: 04 August 2017
Extract
Six years ago an observational program on supergiant stars using CORAVEL was initiated at Geneva Observatory. About 1500 radial velocities were obtained out of a sample of 181 northern supergiants of F, G, K, M type. Nineteen new SB have been discovered and 16 others are suspected to be SB. The total rate of binary systems among northern supergiants is in the range of 31–38 % (Burki and Mayor, 1983). This value neither depends on spectral type nor luminosity class.
