cds-question@unistra.fropen-star-clustersspectroscopychemical-abundancesWe derive the effective temperatures and gravities of 461 OB stars in 19 young clusters by fitting the H{gamma} profile in their spectra. We use synthetic model profiles for rotating stars to develop a method to estimate the polar gravity for these stars, which we argue is a useful indicator of their evolutionary status. We combine these results with projected rotational velocity measurements obtained in a previous paper on these same open clusters.2006ApJ...648..591Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/648/591CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/648/580 : Rotational velocities of 19 open clusters (Huang+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/648/591https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/648/591http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/648/591https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/648/591https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/648/591http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/648/591GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/648/591/table1 (Stellar Physical Parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/648/591/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/648/591/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/648/591/table1?GETtext/xml+votable180.050000true305.039906438.65896440.0055555555555555566/2940 3256 3257 3258 3307 3310 3384 3649 14646 14647 15662 15663 15748 15749 21528 21529 21531 22243 22246 22249 22252 37865 37867 37891 37894 37897 37900 38016 38018 38024 39804 39907 39910 39931 39934 42191 42212 42213 43027 43030 43033 43036https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/648/591?format=asciiOpticaldefaultJ/ApJ/648/591/table1Stellar Physical ParametersrecnoRecord number assigned by the VizieR team.
