cds-question@unistra.frgiant-starschemical-abundancesThis paper investigates the peculiar behaviour of the light elements (even, e.e. alpha-elements, and odd atomic numbers) in red giants of the galactic bulge, both in terms of the chemical evolution of the bulge, and in terms of possible deep-mixing mechanisms in these evolved stars. Abundances of the four light elements O, Na, Mg, and Al are measured in 13 core He-burning giant stars (red clump stars) and 40 red giant branch stars in four 25' fields spanning the bulge from -3 to -12{deg} galactic latitude. Special care was taken in the abundance analysis, performing a differential analysis with respect to the metal-rich solar-neighbourhood giant mu Leo, which best resembles our bulge sample stars. This approach minimises systematic effects that can arise in the analysis of cool metal-rich stars due to continuum definition issues and blending by molecular lines (CN) and, cancels out possible model atmosphere deficiencies.2007A&A...465..799Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/465/799CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/465/799https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/465/799http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/465/799https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/465/799https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/465/799http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/465/799GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/465/799/table1Adopted stellar parameters and heliocentric radial velocity for the Bulge sample starsrecnoRecord number assigned by the VizieR team.
