cds-question@unistra.frspectroscopic-binary-starsradial-velocityspectroscopyInternal kinematics, spectroscopic binaries and galactic motion are investigated for the trapezium system BD+00 1617 (which lies at the heart of the young open cluster Bochum 2) by means on 73 high resolution Echelle+CCD spectra secured over the period 1994-98. Two of the three O-type member stars are found to be binaries on close and highly eccentric orbits of 6.8 and 11.0 day period. Tables 2 and 3, that are available only in electronic form, give the journal of the observations and the individual radial velocities.1999A&A...343..806Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/343/806CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/343/806https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/343/806http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/343/806https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/343/806https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/343/806http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/343/806GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/343/806/table2Journal of ObservationsRes[fb] Resolution (1)meta.codecharrecnoRecord number assigned by the VizieR team.
