cds-question@unistra.frline-intensitiesb-starschemical-abundancesWe present an analysis of high-resolution FLAMES spectra of approximately 50 early B-type stars in three young clusters at different metallicities, NGC 6611 in the Galaxy, N 11 in the Large Magellanic Cloud (LMC) and NGC 346 in the Small Magellanic Cloud (SMC). Using the TLUSTY non-LTE model atmospheres code, atmospheric parameters and photospheric abundances (C, N, O, Mg and Si) of each star have been determined. These results represent a significant improvement on the number of Magellanic Cloud B-type stars with detailed and homogeneous estimates of their atmospheric parameters and chemical compositions. The relationships between effective temperature and spectral type are discussed for all three metallicity regimes, with the effective temperature for a given spectral type increasing as one moves to a lower metallicity regime. Additionally the difficulties in estimating the microturbulent velocity and the anomalous values obtained, particularly in the lowest metallicity regime, are discussed. Our chemical composition estimates are compared with previous studies, both stellar and interstellar with, in general, encouraging agreement being found.2007A&A...466..277Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/466/277CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/437/467 : VLT-FLAMES survey of massive stars (Evans+, 2005)J/A+A/457/265 : VLT-FLAMES Survey of massive Stars (Dufton+, 2006)J/A+A/456/623 : VLT-FLAMES survey of massive stars (Evans+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/466/277https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/466/277http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/466/277https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/466/277https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/466/277http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/466/277GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/466/277/stars (Star positions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/466/277/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/466/277/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/466/277/stars?GETtext/xml+votable180.050000true74.286875-66.39030560.0055555555555555566/29463 33126 33317 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/466/277?format=asciiOpticaldefaultJ/A+A/466/277/starsStar positionsrecnoRecord number assigned by the VizieR team.
