cds-question@unistra.frgiant-starshorizontal-branch-starschemical-abundancesvisible-astronomyLithium and the carbon isotope ratio ^12^C/^13^C can change during the red giant branch as a result of extra-mixing. This is associated usually with thermohaline mixing acting after the RGB bump. Peculiar Li-enriched RGB stars might also be related to either enhanced extra-mixing or pollution from external sources. We measure the Li abundance and ^12^C/^13^C in a sample of 166 field giants targeted by the EXPRESS radial velocity program to analyze the effects of extra-mixing. We measure the abundances with spectral synthesis using high-resolution and high signal-to-noise spectra. Multiple-epoch observations needed for exoplanet detection are used to decrease the effects of telluric contamination in ^12^C/^13^C measurements.2023A&A...670A..73Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/670/A73CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/647/A157 : Stellar parameters of the EXPRESS sample (Soto+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/670/A73https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/670/A73http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/670/A73https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/670/A73https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/670/A73http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/670/A73GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/670/A73/table2 (Catalogue of parameters and measured Li and ^12^C/^13^C for the giants)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/670/A73/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/670/A73/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/670/A73/table2?GETtext/xml+votable180.050000true0.7522306-34.74393810.0055555555555555566/16433 16436 16496 16889 16956 17159 17183 17262 17285 17296 17361 17502 17551 17568 17608 17723 17764 18051 18512 20614 21174 21182 21221 21233 22553 22705 22710 22827 22841 23048 23057 23097 24703 24858 24863 25452 25531 25669 25924 26198 28908 29246 29296 29319 29657 29666 30100 30116 30770 31104 31310 31369 33338 33350 33879 34077 34255 34263 34343 34510 34730 34753 34773 34777 34847 34902 35225 35287 35382 35690 35740 35984 36292 36360 36374 36414 36579 36679 36689 38270 39009 39093 39183 40103 40865 41258 41316 41515 41594 41627 41701 41710 41726 41775 41975 42254 42271 42424 42462 42473 42604 42661 42750 42766 43074 43176 43178 43183 43227 43275 43386 43424 43430 43442 43602 43640 43840 43889 43894 43916 43922 43929 44158 44204 44240 44333 44347 44522 44642 45011 45036 45217 45307 45378 45413 45489 45552 46047 46110 46176 46308 46528 46714 46775 46960 47067 47078 47098 47312 47396 47433 47632 47688 47807 48094 48109 48134 48232 48262 48585 48615 48687 48694 48966 48987 49130https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/670/A73?format=asciiOpticaldefaultJ/A+A/670/A73/table2Catalogue of parameters and measured Li and ^12^C/^13^C for the giantsSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
