cds-question@unistra.frvariable-starschemical-abundancesUsing an Non-Local Thermodynamic Equilibrium (NLTE) analysis and a homogenous spectral data base, we have determined Ba abundances in a sample of 210 Galactic Cepheids and related objects. We confirm the previous result reported in Andrievsky et al. that the barium distribution in the range of Galactocentric distances from 5 to 18kpc shows very small gradient value. The value determined here - d[Ba/H]/dR~-0.01dex/kpc - is smaller than that for other s-process elements, such as La, Pr, Nd and Sm (Luck & Lambert, 2011AJ....142..136L, Cat. J/AJ/142/136), that typically show gradients of -0.03dex/kpc.2014MNRAS.437.2106Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/437/2106CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/142/136 : Spectroscopy of Cepheids. l=30-250{deg} (Luck+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/437/2106https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/437/2106http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/437/2106https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/437/2106https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/437/2106http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/437/2106GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/437/2106/table1 (Parameters and abundances for programme Cepheids)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/437/2106/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/437/2106/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/437/2106/table1?GETtext/xml+votable180.050000true91.645614426.32922140.0055555555555555566/1239 1331 1340 1348 1388 1402 1411 1421 1426 1429 1431-1432 1441 1445 1467 1625 1631 1765 1824 1829 1836 1858 1920 1935 1985 3008 3022 3033 3050 3052 3054 3059-3060 3063 3131 3157 3182 3252 3255 3261 3263 3284-3285 3304 3306 3322 3328 3336-3337 3342 3361-3362 3365 3459 3589 3599-3601 3627 3629 3631 3645 3656 3663 3712-3713 3722 3728 3731 12436 12685 12846 12963 12970-12971 13933 14047 14075 14199 14212 14238-14239 14246 14251 14260 14262 14267 14282 14291-14292 14295 14301 14314 14317 14320-14321 14329 14407 14409 14411 14427 14430 14445 14449 14453 14455 14457 14469 14602 14625 14629-14630 14634 14640 14653 14690 14698 14736 15378 15392-15393 15461 15585 15632-15633 15639 15698 21671 21679 21683 21686 22020 22044 22064 22068-22069 22071 22074 22106 22115-22116 22122 22124 22169 22207 22210 22214 22219 22221 22223 22227 22255 22267 22438 23635 23669-23670 23762 23778 23816 23841 23846 23852 23922 24002 24326 24340 24372 24411 24424 24450 24453 24478-24479 24527 24551 29533 29852 29897 29999 30211 30222-30223 30235 30245 30258 30265 30270 30307 30311 30321 30333 30504 30596 30641 30646 32012 32064https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/437/2106?format=asciiOpticaldefaultJ/MNRAS/437/2106/table1Parameters and abundances for programme CepheidsrecnoRecord number assigned by the VizieR team.
