cds-question@unistra.frmultiple-starssolar-system-planetschemical-abundancesWe explore condensation temperature Tc trends in the binary system zet1 Ret - zet2 Ret, to determine whether there is a depletion of refractories, which could be related to the planet formation process. The star zet2 Ret hosts a debris disk which was detected by an IR excess and confirmed by direct imaging and numerical simulations, while zet1 Ret does not present IR excess nor planets. We derived differential abundances of 24 different species with equivalent widths and spectral synthesis. The star zet1 Ret resulted slightly more metal rich than zet2 Ret by 0.02dex, and the relative abundances showed a positive Tc trend. Then, we propose an scenario in which the refractory elements depleted in zet2 Ret are possibly locked-up in the rocky material that orbits this star and produce the debris disk observed around this object.2016A&A...588A..81Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/588/A81CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/588/A81https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/588/A81http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/588/A81https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/588/A81https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/588/A81http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/588/A81GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/588/A81/table3Differential abundances and errors for the stars zet1 Ret and zet2 RetrecnoRecord number assigned by the VizieR team.
