cds-question@unistra.frg-starsdwarf-starschemical-abundancesWe derive the abundance of 19 elements in a sample of 64 stars with fundamental parameters very similar to solar, which minimizes the impact of systematic errors in our spectroscopic 1D-LTE differential analysis, using high-resolution (R~60000), high signal-to-noise ratio (S/N~200) spectra. The estimated errors in the elemental abundances relative to solar are as small as ~0.025dex. The abundance ratios [X/Fe] as a function of [Fe/H] agree closely with previously established patterns of Galactic thin-disk chemical evolution.2009A&A...508L..17Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/508/L17CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)J/A+A/468/663 : Li abundances in solar-analog stars (Takeda+, 2007)J/ApJS/181/62 : Survey of young solar analogs (Metchev+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/508/L17https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/508/L17http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/508/L17https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/508/L17https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/508/L17http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/508/L17GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/508/L17/sun_twins (Stellar parameters and detailed abundances of solar analogs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/508/L17/sun_twins?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/508/L17/sun_twins?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/508/L17/sun_twins?GETtext/xml+votable180.050000true1.089593112.95729250.0055555555555555566/222 618 634 2152 2780 3044 3102 3436 5263 6043 6087 6217 7217 7540 7587 7763 8244 8790 8979 9406 9756 9805 9932 9996 11212 12592 12922 13353 15174 15336 15739 17266 17473 17572 18041 18209 18773 19655 19884 20145 21114 21251 23150 24212 25755 26496 26549 27254 28542 28605 30878 31132 32575 32730 36453 36517 36590 39801 48310 48345 48450 48487https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/508/L17?format=asciiOpticaldefaultJ/A+A/508/L17/sun_twinsStellar parameters and detailed abundances of solar analogsrecnoRecord number assigned by the VizieR team.
