cds-question@unistra.frmultiple-starsspectroscopychemical-abundancesWe present results of the comparative analysis of the two wide binary systems - 16 Cyg, with a giant gas planet orbiting around 16 Cyg B, and HD 219542 without planet detected. Atmospheric parameters of the binary components and the Sun were determined using their high-resolution spectra and the SME tools for automatic spectral analysis. By applying the synthetic spectrum method, we derived abundances of 29 and 23 chemical elements in 16 Cyg and HD 219542, respectively. For 19 of these elements, our results are based on the non-local thermodynamic equilibrium line formation. For both 16 Cyg and HD 219542, we obtained a small abundance difference between the A and B components: +0.019+/-0.012 and -0.014+/-0.019, respectively, suggesting only a weak influence of the giant gas planet formation on chemical composition of the host star atmosphere. For HD 219542 A and B, trends of the relative-to-solar abundances with the dust condensation temperature are similar to the literature data for the solar analogues without detected planets. The components of 16 Cyg reveal very similar behaviour of [X/H] with the condensation temperature; however, it is different from that for HD 219542. This indicates a specific chemical composition of the cloud from which the 16 Cyg binary system formed.2022MNRAS.514.4958Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/514/4958CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/514/4958https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/514/4958http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/514/4958https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/514/4958https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/514/4958http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/514/4958GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/514/4958/linelistNLTE abundances from individual lines in the Sun, 16 Cyg A and B components, HD 219542 A and B components together with the line atomic parameters and the references to themrecnoRecord number assigned by the VizieR team.
