cds-question@unistra.frb-starschemical-abundanceseffective-temperaturestellar-distanceEarly B-type stars are ideal indicators for present-day cosmic abundances since they preserve their pristine abundances and typically do not migrate far beyond their birth environments over their short lifetimes, in contrast to older stars like the Sun. They are also unaffected by depletion onto dust grains, unlike the cold/warm interstellar medium (ISM) or HII regions. A carefully selected sample of early B-type stars in OB associations and the field within the solar neighbourhood is studied comprehensively. Quantitative spectroscopy is used to characterise their atmospheric properties in a self-consistent way. Present-day abundances for the astrophysically most interesting chemical elements are derived in order to investigate whether a present-day cosmic abundance standard can be established.2012A&A...539A.143Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/539/A143CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/539/A143https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/539/A143http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/539/A143https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/539/A143https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/539/A143http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/539/A143GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/539/A143/Bstars (Stellar parameters and metal abundances for the sample stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/539/A143/Bstars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/539/A143/Bstars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/539/A143/Bstars?GETtext/xml+votable180.050000true83.1723058-1.59183080.0055555555555555566/2970 9680 13722 16144 17754 19336 19676 21233 21432 21438 22772 22859 22889 23717 24186 39297 40068 40617 42948 43414https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/539/A143?format=asciidefaultJ/A+A/539/A143/BstarsStellar parameters and metal abundances for the sample starsrecnoRecord number assigned by the VizieR team.
