cds-question@unistra.frmultiple-starsexoplanetsline-intensitieschemical-abundancesWe present a line-by-line differential analysis of a sample of 16 planet-hosting stars and 68 comparison stars using high-resolution, high signal-to-noise ratio spectra gathered using Keck. We obtained accurate stellar parameters and high-precision relative chemical abundances with average uncertainties in Teff, logg, [Fe/H], and [X/H] of 15K, 0.034cm/s^2^, 0.012dex, and 0.025dex, respectively. For each planet host, we identify a set of comparison stars and examine the abundance differences (corrected for Galactic chemical evolution effect) as a function of the dust condensation temperature, Tcond, of the individual elements. While we confirm that the Sun exhibits a negative trend between abundance and Tcond, we also confirm that the remaining planet hosts exhibit a variety of abundance-Tcond trends with no clear dependence upon age, metallicity, or Teff. The diversity in the chemical compositions of planet-hosting stars relative to their comparison stars could reflect the range of possible planet-induced effects present in these planet hosts, from the sequestration of rocky material (refractory poor) to the possible ingestion of planets (refractory rich). Other possible explanations include differences in the time-scale, efficiency and degree of planet formation, or inhomogeneous chemical evolution. Although we do not find an unambiguous chemical signature of planet formation among our sample, the high-precision chemical abundances of the host stars are essential for constraining the composition and structure of their exoplanets.2020MNRAS.495.3961Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/495/3961CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/495/3961https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/495/3961http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/495/3961https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/495/3961https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/495/3961http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/495/3961GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/495/3961/table1 (Stellar parameters and ages for the program stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/3961/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/3961/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/3961/table1?GETtext/xml+votable180.050000true6/634 2476 2818 2922 4665 5304 5836 6026 8345 8881 9026 9492 9883 10598 10914 11858 12337 12846 12899 12944 13495 13763 13768 14144 14181 14419 14531 14539 14585 14734 14918 14933 14936 14968 15030 15121 15131 15145 15174 17266 17576 17588 17730 17804 17835 17944 18361 18748 20072 20124 20145 20328 25407 25567 25595 25614 25862 26462 28868 29210 29238 30278 30579 30665 30691 30878 31015 31130 31145 31433 31532 31970 31984 32561 32596 36813 40442 42845 42874 42981 44398https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/495/3961?format=asciidefaultJ/MNRAS/495/3961/table1Stellar parameters and ages for the program starsNameNamemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
