Scientific paper

The correlation between the space velocity and cyanogen anomaly for G- and K-stars, which had been discovered earlier, is partly confirmed in the present investigation. It has been examined by means of radial velocities, but it is not confirmed for giants, supergiants and dwarfs. Only a small number of subgiants fall into kinematically extreme groups as a function of the sign of the CN-index difference. Small systematic errors in the absolute magnitudes, an admixture of subgiants, and a group of giant stars with high tangential but small radial velocities may be the main reasons for the discrepancy between the results obtained by means of radial and space velocities.
