cds-question@unistra.fropen-star-clustersearly-type-starschemical-abundancesWe have previously analysed the spectra of 135 early B-type stars in the Large Magellanic Cloud (LMC) and found several groups of stars that have chemical compositions that conflict with the theory of rotational mixing. Here we extend this study to Galactic and Small Magellanic Cloud (SMC) metallicities. We provide chemical compositions for ~50 Galactic and ~100 SMC early B-type stars and compare these to the LMC results. These samples cover a range of projected rotational velocities up to ~300km/s and hence are well suited to testing rotational mixing models. The surface nitrogen abundances are utilised as a probe of the mixing process since nitrogen is synthesized in the core of the stars and mixed to the surface.2009A&A...496..841Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/496/841CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/437/467 : VLT-FLAMES survey of massive stars (Evans+, 2005)J/A+A/456/623 : VLT-FLAMES survey of massive stars (Evans+, 2006)J/A+A/457/265 : VLT-FLAMES survey of massive stars (Dufton+, 2006)J/A+A/466/277 : VLT-FLAMES survey of massive stars (Hunter+, 2007)J/A+A/471/625 : VLT-FLAMES survey of massive stars (Trundle+, 2007)J/A+A/479/541 : VLT-FLAMES survey of massive stars (Hunter+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/496/841https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/496/841http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/496/841https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/496/841https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/496/841http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/496/841GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/496/841/table2 (Atmospheric parameters, projected rotational velocities and chemical compositions of the sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/496/841/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/496/841/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/496/841/table2?GETtext/xml+votable180.050000true274.7445464-13.99123310.0055555555555555566/29463 29506 33112 33126 33295 33317 33328 38018-38019 38024 43033 43036https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/496/841?format=asciiOpticaldefaultJ/A+A/496/841/table2Atmospheric parameters, projected rotational velocities and chemical compositions of the samplerecnoRecord number assigned by the VizieR team.
