SB9: The Ninth Catalogue of Spectroscopic Binary Orbits

The Ninth Catalogue of Spectroscopic Binary Orbits (http://sb9.astro.ulb.ac.be) continues the series of compilations of spectroscopic orbits carried out over the past 35 years by Batten and collaborators. As of 2004 May 1st, the new Catalogue holds orbits for 2,386 systems. Some essential differences between this catalogue and its predecessors are outlined and three straightforward applications are presented: (1) Completeness assessment: period distribution of SB1s and SB2s; (2) Shortest periods across the H-R diagram; (3) Period-eccentricity relation.

Spectroscopic binaries in the open cluster Trumpler 16 revisited

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. Also, we have also tried to find the orbital periods for two suspected binary systems in the same cluster. We have improved considerably the precision of some of the orbital parameters.
