cds-question@unistra.frh-ii-regionsstar-forming-regionsb-starsspectroscopic-binary-starsradial-velocityapparent-magnitudeThe Carina Nebula is an active star-forming region in the southern sky that is of particular interest due to the presence of a large number of massive stars in a wide array of evolutionary stages. Here, we present the results of the spectroscopic analysis of 82 B-type stars and 33 O-type stars that were observed in 2013 and 2014. For 82 B-type stars without line blending, we fit model spectra from the Tlusty BSTAR2006 grid to the observed profiles of H{gamma} and He {lambda}{lambda}4026, 4388, and 4471 to measure the effective temperatures, surface gravities, and projected rotational velocities. We also measure the masses, ages, radii, bolometric luminosities, and distances of these stars. From the radial velocities measured in our sample, we find 31 single lined spectroscopic binary candidates. We find a high dispersion of radial velocities among our sample stars, and we argue that the Carina Nebula stellar population has not yet relaxed and become virialized.2018AJ....155..190Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/155/190CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/469/355 : Teff, B-V and BC relation (Flower, 1996)J/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)J/ApJS/194/5 : Carina OB stars in the CCCP catalog (Gagne+, 2011)J/ApJS/194/6 : Candidate X-ray emitting OB stars in Carina (Povich+, 2011)J/ApJS/194/7 : Global X-ray properties of O and B stars in CarinaJ/ApJS/194/14 : A Pan-Carina YSO catalog (Povich+, 2011)J/A+A/572/A116 : The VISTA Carina Nebula Survey (Preibisch+, 2014)J/MNRAS/465/1807 : Deep OB star population in Carina (Mohr-Smith+, 2017)J/MNRAS/477/2068 : RV survey of the Carina Nebula's O stars (Kiminki+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/155/190https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/155/190http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/155/190https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/155/190https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/155/190http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/155/190GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/155/190/OBstars (Radial velocity measurements of B-type (table 3) and O-type stars (table 4))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/155/190/OBstars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/155/190/OBstars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/155/190/OBstars?GETtext/xml+votable180.050000true161.7883539-59.79160920.005555555555555556Cone search capability for table J/AJ/155/190/table5 (Radial velocity measurements of SB2s)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/155/190/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/155/190/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/155/190/table5?GETtext/xml+votable180.050000true160.7090461-59.42532080.005555555555555556Cone search capability for table J/AJ/155/190/Parameters (Projected rotational velocities (table 1) , physical parameters (table 2) , photometry and derived distances (table 6))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/155/190/Parameters?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/155/190/Parameters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/155/190/Parameters?GETtext/xml+votable180.050000true161.7883539-59.79160920.0055555555555555566/37247 37333 37335 37930 38016 38018https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/155/190?format=asciidefaultJ/AJ/155/190/OBstarsRadial velocity measurements of B-type (table 3) and O-type stars (table 4)SimbadNameSimbad column added by the CDSmeta.idcharTypeStellar typesrc.classcharIDStar identifiermeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
