cds-question@unistra.fro-starsradial-velocityeffective-temperaturestellar-spectral-typesWe present radial velocities for 18 Galactic O-type stars. These stars display small radial velocity scatter over timescales of one to two weeks. Some of them are long-period binaries while others are probably single stars. By fitting model spectra to our observed spectra we obtain estimates for effective temperature, log g, rotational velocity, and average radial velocity for each target.2011AJ....142..146Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/142/146CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/84 : Galactic O Stars (Cruz-Gonzalez+ 1974)II/82 : Galactic O-type Stars (Garmany+ 1982)V/116 : Galactic O star catalog (Maiz-Apellaniz+, 2004)III/252 : Pulkovo radial velocities for 35493 HIP stars (Gontcharov, 2006)III/254 : 2nd Cat. of RVs with Astrometric Data (Kharchenko+, 2007)J/A+A/437/467 : VLT-FLAMES survey of massive stars (Evans+, 2005)J/AJ/137/3358 : Speckle interferometry of massive stars (Mason+, 2009)J/other/Sci/337.444 : RV curves of Galactic massive O stars (Sana+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/142/146https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/142/146http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/142/146https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/142/146https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/142/146http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/142/146GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/142/146/table2 (Individual stellar parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/142/146/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/142/146/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/142/146/table2?GETtext/xml+votable180.050000true23.136348161.12939220.0055555555555555566/3331 3622 3644 14353 14646 28890 37863 37897 37901 37926 38016 39804 41903 42438https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/142/146?format=asciiOpticaldefaultJ/AJ/142/146/table2Individual stellar parametersSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
