| 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 ofspectroscopic orbits carried out over the past 35 years by Batten andcollaborators. As of 2004 May 1st, the new Catalogue holds orbits for2386 systems. Some essential differences between this catalogue and itspredecessors are outlined and three straightforward applications arepresented: (1) completeness assessment: period distribution of SB1s andSB2s; (2) shortest periods across the H-R diagram; (3)period-eccentricity relation.
| Spectroscopic binaries near the North Galactic Pole. XXI - Eight short-period binaries
Orbits based principally on radial-velocity measurements made with theHaute-Provence Coravel spectrometer are presented for eight binarysystems which include some of the faintest HD stars in the Galactic-Polefield. They are HD 103418 (which is double-lined), 105021, 108151,113169, 113323, 113650, 113714, and 116514. Their periods range from 3.7to 15.1 days. Very little else is known about any of them.
