Abstract

From spectrographic observations of probable members of NGC 6193 we have obtained their radial velocities, projected axial rotational velocities, and approximate spectral types. We computed the average axial rotation with respect to the field stars for the members of NGC 6193 as 0.67 ± 0.08 and an average heliocentric radial velocity for the cluster of –33. km sec⁻¹. Six new spectroscopie binaries and a He-rich star were discovered. We compare the high incidence of spectroscopie binaries among the main-sequence members of NGC 6193 with clusters of similar average axial rotation.
