cds-question@unistra.frmagellanic-cloudschemical-abundancesWe have used FLAMES (the Fibre Large Array Multi Element Spectrograph) at the VLT-UT2 telescope to obtain spectra of a large sample of red giant stars from the inner disk of the LMC, ~2kpc from the center of the galaxy. We investigate the chemical abundances of key elements to understand the star formation and evolution of the LMC disk: heavy and light [s-process/Fe] and [alpha/Fe] give constraints on the time scales of formation of the stellar population. Cu, Na, Sc, and the iron-peak elements are also studied aiming to better understand the build up of the elements of this population and the origin of these elements. We aim to provide a more complete picture of the LMC's evolution by compiling a large sample of field star abundances. LTE abundances were derived using line spectrum synthesis or equivalent width analysis. We used OSMARCS model atmospheres and an updated line list.2008A&A...480..379Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/480/379CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/480/379https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/480/379http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/480/379https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/480/379https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/480/379http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/480/379GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/480/379/stars (Photometry and abundances of the observed stars (tables 1, 5-8 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/480/379/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/480/379/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/480/379/stars?GETtext/xml+votable180.050000true77.8961667-71.20858330.0055555555555555566/33051 330548.650015785639275e-20 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/480/379?format=asciidefaultJ/A+A/480/379/table3Errors due to stellar parameters uncertaintiesrecnoRecord number assigned by the VizieR team.
