cds-question@unistra.frlate-type-starschemical-abundancesvisible-astronomyHighly differential spectroscopic studies have revealed that the Sun is deficient in refractory elements relative to solar twins. To investigate the role of giant planets on this signature, we present a high precision abundance analysis of HARPS spectra for 50 F- and G-type stars spanning -0.4<~[Fe/H]<~+0.5. There are 29 stars in the sample which host planets of masses >~0.01M_jup_. We derive abundances for 19 elements, and apply corrections to 14 of them for systematic errors associated with one dimensional (1D) model atmospheres, or the assumption of local thermodynamic equilibrium (LTE), or both. We find that, among the solar twins in our sample, the Sun is Li poor in comparison to other stars at similar age, in agreement to previous studies. The sample shows a variety of trends in elemental abundances as a function of condensation temperature. We find a strong correlation in these trends with [Fe/H], with a marginally-significant difference in the gradients for stars with and without giants planets detected, that increases after applying 3D and non-LTE corrections. Our overall results suggests that the peculiar composition of the Sun is primarily related to Galactic chemical evolution rather than the presence of giant planets.2025A&A...700A.127Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/700/A127CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/700/A127https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/700/A127http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/700/A127https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/700/A127https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/700/A127http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/700/A127GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/700/A127/table1 (Stellar parameters, ages and number of planets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/700/A127/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/700/A127/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/700/A127/table1?GETtext/xml+votable180.050000true310.04898-23.773870.0055555555555555566/16652 16883 17730 17768 18548 19003 22590 24924 25225 25862 26768 27018 30526 30878 31029 32930 33063 33630 33923 35954 37573 38238 38279 40101 40442 40692 40921 41861 41912 42146 42248 42700 43228 43258 43639 43760 43813 43911 44131 44243 44740 45121 45364 45669 45865 46297 46306 46640 48545 48705https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/700/A127?format=asciiOpticaldefaultJ/A+A/700/A127/table1Stellar parameters, ages and number of planetsrecnoRecord number assigned by the VizieR team.
