cds-question@unistra.frmultiple-starssolar-system-planetschemical-abundancesWe explore condensation temperature Tc trends and the Li content in the binary system HAT-P-4, to study the possible chemical signature of planet formation. The star HAT-P-4 hosts a hot Jupiter planet detected by transits, while its stellar companion does not have any detected planets. We derived the fundamental parameters and abundances using the differential method. HAT-P-4 is found to be about 0.1dex more metal rich than its companion; it is enhanced in refractory elements and presents a higher Lithium content. We propose a scenario of a possible rocky planet engulfment in HAT-P-4, which explains the higher metallicity, the higher Li content, and the negative Tc trend we detected.2017A&A...604L...4Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/604/L4CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/141/63 : Relative radial velocities of HAT-P-4 and HAT-P-14 (Winn+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/604/L4https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/604/L4http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/604/L4https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/604/L4https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/604/L4http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/604/L4GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/604/L4/list (List of fits spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/604/L4/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/604/L4/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/604/L4/list?GETtext/xml+votable180.050000true229.99137536.22966670.0055555555555555566/9173https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/604/L4?format=asciidefaultJ/A+A/604/L4/table1Line list and equivalent widths of stars A, B and SunrecnoRecord number assigned by the VizieR team.
