Spectroscopic binaries in the open cluster Trumpler 16 revisited.

LUNA G.J., LEVATO H., MALARODA S. and GROSSO M.

Abstract (from CDS):

We have recalculated the orbits of 3 binary systems, members of the open cluster Trumpler 16 in the Carina region. We have added new observations to those available in the literature. We have improved considerably the precision of some of the orbital parameters. We could not find significant radial velocity variations for two suspected binary systems in the same cluster.
