cds-question@unistra.frmilky-way-galaxydwarf-starschemical-abundancesLithium abundance in most of the warm metal-poor main sequence stars shows a constant plateau (A(Li)~2.2dex) and then the upper envelope of the lithium vs. metallicity distribution increases as we approach solar metallicity. Meteorites, which carry information about the chemical composition of the interstellar medium at the solar system formation time, show a lithium abundance A(Li)~3.26dex. This pattern reflects the Li enrichment history of the interstellar medium during the Galaxy lifetime. After the initial Li production in Big Bang Nucleosynthesis, the sources of the enrichment include AGB stars, low-mass red giants, novae, type II supernovae, and Galactic cosmic rays. The total amount of enriched Li is sensitive to the relative contribution of these sources. Thus different Li enrichment histories are expected in the Galactic thick and thin disc. We investigate the main sequence stars observed with UVES in Gaia-ESO Survey iDR4 catalog and find a Li-[alpha/Fe] anticorrelation independent of [Fe/H], Teff, and log(g). Since in stellar evolution different {alpha} enhancements at the same metallicity do not lead to a measurable Li abundance change, the anticorrelation indicates that more Li is produced during the Galactic thin disc phase than during the Galactic thick disc phase. We also find a correlation between the abundance of Li and s-process elements Ba and Y, and they both decrease above the solar metallicity, which can be explained in the framework of the adopted Galactic chemical evolution models.2018A&A...610A..38Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/610/A38CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/574/L7 : Gaia-ESO Survey: Li-rich stars in NGC2547 (Sacco+, 2015)J/A+A/598/A5 : Gaia-ESO Survey iDR4 calibrators (Pancino+, 2017)J/A+A/601/A112 : GES iDR4 Mg-Al anticorrelation in GCs (Pancino+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/610/A38https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/610/A38http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/610/A38https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/610/A38https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/610/A38http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/610/A38GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/610/A38/table1 (Stellar parameters, the selected chemical abundances, and their corresponding uncertainties of stars in our final sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/610/A38/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/610/A38/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/610/A38/table1?GETtext/xml+votable180.050000true278.610375-27.12141670.0055555555555555565/9673 6/17299-17300 17302 17374 17379 17382 17403 17405 17649 17651 17693 17714 17720 17725 17741 17748 17768 17794 17816 17826-17827 17966 17969 17985 18003 18017 18062 18068 18088 18366 18621 18639 18645 18677 18710 18724-18725 18743 18765 18834 18848 18974 18996 19006 19027 19079 19092 19104 21594-21595 21778 21839 21850 21912-21913 22078-22079 22099 22102 22945 23123 23189 23191 23204 23497 24576 24589-24591 25074 25247 25262-25263 25277 25314 25320 25326 25392 25445 25487 25498 25512 25536 25645 25688-25689 25727 25756 25813 25827 25830 25880 26112 26126 26692 26792 26803 27172 27288 28737 28743 28797 28938 28968 30295 30472 30904 30906 31017 31236 31332 33238 33253 33257 33278 33596-33598 33607 33618 33633 33661 33682 33702 33726 33739 33746 33751 33761 33771 33776 33813 33818 33826-33827 33834 33854 33894-33895 33927 33933 33953 33988 33995 34007 34017-34018 34027 34033 34035 34073 34075 34078 34093 34178 34318 34320-34321 34334 34348-34349 34369 34434 34726 34879 34901 34905 34907 34918 34922 34939 34969 34982 34984 34986 35005 35022 35025 35031 35051 35056 35072 35085 35102 35106 35117 35344 35346 35356 35358 35361 35373 35387 35456 36106 38240 38252 38299 38302 38316 38363-38364 38490-38491 38503 38656 38678 38684 39332 39503 40021 40301 40312 40349 40370 40392 40445 40667 40746-40747 40752 40818 40881 42309 42325 42340 42555 42604 42606 42639 42648-42649 42654 42663 42668 43245 43255-43256 43261 43311 43319 43322 43354 43360 43371 43376-43377 43389 43397 43419 43430-43431 43436-43437 43469 43480 43505-43506 43508 43512 43593 43605 43611 43623 43675 43692 43710 43712 43776 43778 43794 43806-43807 43809 44032 44034 44036 44047 44287 44392 44431 44440 44451-44453 44507 44514 44648 44760 44815 44819 44888-44889 44906 44968 44970 44972 45007 45556 45567 45887 45912 45925 45944 45971 45976-45977 45990 46037 46039 46059 46064 46143 46162 46165 46168 46179 46182 46203 46206 46224 46226-46227 46232 46243 46246 46263 46274 46285 46295 46306 46309 46343 46354 46357 46366 46368 46377 46380 46436 46466 46617 46659 46733 47319 47339 47388 47390 47405 47416 47418 47490 47644 47646 47661 47679 47716 47720 47749-47751 47753-47754 47764-47765 47780-47781 47786 47809 47812 49141 49151https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/610/A38?format=asciidefaultJ/A+A/610/A38/table1Stellar parameters, the selected chemical abundances, and their corresponding uncertainties of stars in our final samplerecnoRecord number assigned by the VizieR team.
