cds-question@unistra.fropen-star-clusterschemically-peculiar-starsHigh-resolution spectroscopy is used to determine the detailed chemical abundances of a group of eight F- and G-type stars in the young open cluster Blanco 1. An average [Fe/H] of +0.04+/-0.02 (internal error)+/-0.04 (external error) is found, considerably lower than a previous spectroscopic estimate for this cluster. The difference is due mainly to our adoption of significantly cooler temperatures that are consistent with both photometric and spectroscopic constraints. Blanco 1 exhibits subsolar [Ni/Fe](0.18+/-0.01+/-0.01), [Si/Fe](0.09+/-0.02+/-0.03), [Mg/Fe](0.14+/-0.02+/-0.03) and [Ca/Fe](0.09+/-0.03+/-0.03); ratios that are not observed among nearby field stars.2005MNRAS.364..272Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/364/272CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/121/213 : BV photometry of Blanco 1 stars (Panagi+, 1997)J/A+AS/76/101 : UBV and uvbyb in zeta Scl cluster (Westerlund+, 1988)J/A+A/399/919 : X-ray Luminosities in Blanco 1 (Pillitteri+, 2003)J/A+A/421/175 : XMM sources in Blanco 1 (Pillitteri+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/364/272https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/364/272http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/364/272https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/364/272https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/364/272http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/364/272GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/364/272/stars (Atmospheric parameters and derived abundances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/364/272/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/364/272/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/364/272/stars?GETtext/xml+votable180.050000true0.8903875-30.2621250.0055555555555555566/16488-16490 16576https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/364/272?format=asciiOpticaldefaultJ/MNRAS/364/272/starsAtmospheric parameters and derived abundancesrecnoRecord number assigned by the VizieR team.
