cds-question@unistra.frvariable-starschemical-abundancesmilky-way-galaxyWe performed a non-local thermodynamic equilibrium (NLTE) analysis of the infrared oxygen triplet for a large number of Cepheid spectra obtained with the Hobby-Eberly Telescope. These data were combined with our previous NLTE results for stars observed with the Max Planck Gesellschaft Telescope with the aim of investigating the oxygen abundance distribution in the Galactic thin disc. We found the slope of the radial (O/H) distribution to be equal -0.058dex/kpc. However, we found some evidence that the distribution might become flatter in the outer parts of the disc. This is supported by the results of other authors who have studied open clusters, planetary nebulae and Hii regions. Some mechanisms of flattening are discussed.2014MNRAS.444.3301Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/444/3301CatalogResearchIsServedByTAP 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/444/3301https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/444/3301http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/444/3301https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/444/3301https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/444/3301http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/444/3301GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/444/3301/table1 (Parameters and abundances for program Cepheids)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/444/3301/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/444/3301/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/444/3301/table1?GETtext/xml+votable180.050000true91.645614426.32922140.0055555555555555566/1239 1331 1340 1348 1388 1402 1411 1421 1426 1429 1431-1432 1441 1445 1467 1625 1765 1824 1829 1836 1858 1920 1985 3022 3033 3050 3052 3054 3059-3060 3063 3252 3255 3261 3263 3284-3285 3304 3306 3322 3342 3362 3365 3459 3589 3599-3601 3627 3629 3645 3656 3712-3713 3722 3731 12846 12963 12968 12970-12971 13933 14047 14212 14238-14239 14246 14251 14260 14262 14267 14282 14291-14292 14295 14301 14320-14321 14407 14409 14411 14427 14430 14445 14449 14455 14457 14469 14602 14625 14629-14630 14634 14640 14653 14690 14698 14736 15378 15392-15393 15461 15632-15633 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 23622 23635 23670 23762 23778 23841 23846 23852 23922 24002 24326 24340 24372 24411 24424 24450 24453 24478-24479 24527 29533 29897 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/444/3301?format=asciiOpticaldefaultJ/MNRAS/444/3301/table1Parameters and abundances for program CepheidsPhase[0/1]?
