cds-question@unistra.frmilky-way-galaxydwarf-starsgiant-starschemical-abundancesspectroscopyDue to their volatile nature, when sulphur and zinc are observed in external galaxies, their determined abundances represent the gas-phase abundances in the interstellar medium. This implies that they can be used as tracers of the chemical enrichment of matter in the Universe at high redshift. Comparable observations in stars are more difficult and, until recently, plagued by small number statistics. We wish to exploit the Gaia ESO Survey (GES) data to study the behaviour of sulphur and zinc abundances of a large number of Galactic stars, in a homogeneous way. By using the UVES spectra of the GES sample, we are able to assemble a sample of 1301 Galactic stars, including stars in open and globular clusters in which both sulphur and zinc were measured. We confirm the results from the literature that sulphur behaves as an alpha-element. We find a large scatter in [Zn/Fe] ratios among giant stars around solar metallicity. The lower ratios are observed in giant stars at Galactocentric distances less than 7.5kpc. No such effect is observed among dwarf stars, since they do not extend to that radius. Given the sample selection, giants and dwarfs are observed at different Galactic locations, and it is plausible, and compatible with simple calculations, that Zn-poor giants trace a younger population more polluted by SN Ia yields. It is necessary to extend observations in order to observe both giants and dwarfs at the same Galactic location. Further theoretical work on the evolution of zinc is also necessary.2017A&A...604A.128Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/604/A128CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/572/A33 : Abundances from Gaia-ESO Survey (Mikolaitis+, 2014)J/A+A/589/A115 : Na and Al abundances of 1303 stars (Smiljanic+, 2016)J/A+A/603/A2 : GES abundances radial distribution (Magrini+, 2017)J/MNRAS/441/3127 : FeI oscillator strengths for Gaia-ESO (Ruffoni+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/604/A128https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/604/A128http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/604/A128https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/604/A128https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/604/A128http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/604/A128GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/604/A128/ges_s_du (Sulphur abundances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/604/A128/ges_s_du?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/604/A128/ges_s_du?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/604/A128/ges_s_du?GETtext/xml+votable180.050000true116.328958328.02619440.0055555555555555565/7184 9838 6/4298 4574 6219 12341 12405 14336 17300 17302 17374 17403 17405 17425 17649 17693 17714 17720 17725 17741 17748 17768 17794 17826-17827 17966 17969 17985 18003 18017 18062 18068 18088 18366 18621 18639 18645 18710 18724 18743 18765 18848 18974 18996 19006 19027 19079 19092 19104 20562 20939 20975 21594-21595 21778 21839 21850 21912-21913 22078-22079 22099 22102 22118 22300 22945 23096 23123 23189 23191 23204 24576 24590-24591 24715 25074 25247 25262-25263 25277 25314 25326 25392 25445 25498 25512 25536 25645 25688-25689 25756 25813 25827 25830 25880 26112 26126 26302 26552 26692 26803 26975 27172 27255 27288 28683 28720 28722 28743 28745 28765 28768 28770 28778 28797 28799 28936 28938 28968 28970 29951 30215 30293 30295 30308 30464 30466 30472-30473 30878 30904 30906 31017 31236 31293 31332 31787 31790 31809 31812 33238 33253 33257 33278 33281 33321 33330 33607 33633 33661 33682 33702 33726 33739 33746 33751 33761 33776 33813 33818 33826-33827 33834 33854 33894-33895 33927 33933 33953 33988 34007 34018 34027 34033 34035 34073 34075 34078 34093 34178 34242 34321 34334 34348-34349 34369 34726 34879 34901 34907 34922 34969 34982 34986 35005 35022 35025 35031 35056 35072 35085 35102 35117 35344 35346 35373 35387 35456 36106 36693 36697 37227 37229-37231 37240-37242 37294 37313 37316-37317 37319 37587 37592-37594 37787-37788 37790 37812 37933 37938 37944 38240 38252 38299 38302 38316 38363-38364 38490-38491 38503 38566 38656 38684 38692 38694-38695 38936 39181 39183 39358 39503 39672 39685 39696-39698 40021 40301 40312 40370 40392 40445 40667 40746-40747 40752 40818 40881 41466 41513 41522 41649 41678 41763 42248 42309 42325 42327 42337 42340 42496 42555 42604 42606 42639 42648-42649 42663 42668 43034 43245 43255-43256 43261 43311 43322 43354 43360 43371 43376-43377 43389 43397 43419 43430-43431 43436-43437 43469 43480 43506 43508 43512 43593 43611 43623 43675 43692 43710 43712 43776 43794 43806-43807 43809 44032 44034 44036 44047 44287 44392 44431 44440 44451 44453 44507 44514 44648 44760 44815 44819 44888-44889 44906 44970 44972 45007 45556 45567 45721 45887 45912 45925 45971 45976-45977 45990 46037 46039 46059 46064 46162 46179 46182 46206 46246 46274 46285 46306 46309 46343 46357 46368 46377 46436 46617 46659 46733 47022 47125 47319 47339 47390 47405 47416 47418 47644 47646 47661 47679 47716 47720 47749 47751 47753-47754 47764-47765 47776 47780-47781 47786 47809 47812 49141 49151https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/604/A128?format=asciiOpticaldefaultJ/A+A/604/A128/ges_s_duSulphur abundancesrecnoRecord number assigned by the VizieR team.
