cds-question@unistra.frmultiple-starssolar-system-planetschemical-abundancesDuring the past decade, several studies reported a correlation between chemical abundances of stars and condensation temperature (also known as Tc trend). However, the real astrophysical nature of this correlation is still debated. The main goal of this work is to explore the possible dependence of the Tc trend on stellar Galactocentric distances, Rmean. We used high-quality spectra of about 40 stars observed with the HARPS and UVES spectrographs to derive precise stellar parameters, chemical abundances, and stellar ages. A differential line-by-line analysis was applied to achieve the highest possible precision in the chemical abundances. We confirm previous results that [X/Fe] abundance ratios depend on stellar age and that for a given age, some elements also show a dependence on Rmean. When using the whole sample of stars, we observe a weak hint that the Tc trend depends on Rmean. The observed dependence is very complex and disappears when only stars with similar ages are considered. To conclude on the possible dependence of the Tc trend on the formation place of stars, a larger sample of stars with very similar atmospheric parameters and stellar ages observed at different Galactocentric distances is needed.2016A&A...592A..87Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/592/A87CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AZh/81/541 : Abundances of 15 solar analogues (Galeev+, 2004)J/A+A/552/A78 : Solar like stars radial velocities (Zechmeister+, 2013)J/A+A/562/A92 : Li abundance in solar analogues (Delgado Mena+, 2014)J/A+A/574/A124 : Spectroscopy of solar twins and analogues (Datson+, 2015)J/A+A/591/A34 : Chemical abundances of zeta Reticuly (Adibekyan+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/592/A87https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/592/A87http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/592/A87https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/592/A87https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/592/A87http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/592/A87GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/592/A87/sample (Stellar parameters of the stars and abundances for each star and element)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/592/A87/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/592/A87/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/592/A87/sample?GETtext/xml+votable180.050000true174.6667361-13.20194330.0055555555555555566/8381 12435 12976 18005 18243 22157 25374 25473 26082 26610 26617 29653 31316 31380 31549 31821 33630 37330 37351 39461 39693 40140 40692 41441 41773 42360 42457 42656 42787 43105 43228 43332 43406 43556 43668 43686 43845 45391 48032https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/592/A87?format=asciidefaultJ/A+A/592/A87/sampleStellar parameters of the stars and abundances for each star and elementrecnoRecord number assigned by the VizieR team.
