cds-question@unistra.frmultiple-starschemical-abundancesspectroscopyThis table presents the results of a spectroscopic analysis (differentially to the Sun) of the two components of the binary system Alpha Centauri. This analysis has been carried out on the basis of extensive high resolution and high signal-to-noise spectra taken at the European Southern Observatory (La Silla, Chile).1997A&A...328..261Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/328/261CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/328/261https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/328/261http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/328/261https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/328/261https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/328/261http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/328/261GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/328/261/table4Spectroscopic data and abundances in Alpha Cen A, Alpha Cen B and the Sun.recnoRecord number assigned by the VizieR team.
