cds-question@unistra.frgiant-starsline-intensitiesWe present our analysis of elemental abundances in the atmospheres of 16 classical barium stars derived from high-resolution spectra and model atmospheres. Comparison of the results with analogous data for moderate barium stars and normal red giants shows that the abundance patterns for elements before the iron peak are the same for all three groups of red giants, testifying to a similar origin. For binary systems, we confirm the influence of the orbital period and, hence, the component separation, on the overabundance of s-process elements. The amount of enrichment in s-process elements is also in influenced by mass, metallicity, and evolutionary phase. Any of these parameters can be important in individual objects.2004AZh....81..658Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/81/658CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AZh/78/807 : Chemical composition of eta Ser (Antipova+, 2001)J/AZh/79/909 : Chemical abundances in barium stars (Boyarchuk+, 2002)J/AZh/80/704 : Studies of classical barium stars (Antipova+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/81/658https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/81/658http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/81/658https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/81/658https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/81/658http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/81/658GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AZh/81/658/stars (List of the 9 stars studied)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/81/658/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/81/658/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/81/658/stars?GETtext/xml+votable180.050000true41.9487581.4486110.0055555555555555566/4041 5624 13244 28959 30640 30659 40311 44488 45027https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/81/658?format=asciiOpticaldefaultJ/AZh/81/658/starsList of the 9 stars studiedBmagBlue magnitude (from Simbad)magfloatrecnoRecord number assigned by the VizieR team.
