Description

The frequency of primordial binary stars in globular clusters is important for our understanding of stellar populations and the dynamical evolution of clusters. We have used radial velocity measurements of giants in the globular clusters 47 Tuc, M 2, M 3, M 12, M 13, and M 71 to identify six stars that are probably binaries. These stars show radial velocity variations larger than 10 km s-1 and are not known to be photometric variables. (author)
