B/sb9 SB9: 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2011) ================================================================================ The Ninth Catalogue of Spectroscopic Binary Orbits (Version 2011May) Pourbaix D., Tokovinin A.A, Batten A.H., Fekel F.C., Hartkopf W.I., Levato H., Morell N.I., Torres G., Udry S. =2004A&A...424..727P ================================================================================ ADC_Keywords: Binaries, orbits ; Binaries, spectroscopic Keywords: stars: binaries: spectroscopic - astronomical data bases: miscellaneous - catalogs Abstract: The Ninth Catalogue of Spectroscopic Binary Orbits continues the series of compilations of spectroscopic orbits carried out over the past 35 years by Batten and collaborators (see e.g. Cat. V/64). The catalogue is continuously updated, see http://sb9.astro.ulb.ac.be/ This version is dated 02-May-2011. Previous versions may be found in subdirectories "v00" (April 2005), "v01" (September 2005), etc...

Note (2): a non-zero value indicates that T0 does not correspond to the periastron epoch, but to some other phenomena (e.g. eclipse) -------------------------------------------------------------------------------- Acknowledgements: This version was prepared with the help of Dimitri Pourbaix.
