cds-question@unistra.frchemical-abundancesline-intensitiessolar-system-planetsmultiple-starsPrecise abundances of 18 elements have been derived for 10 stars known to host giant planets from high signal-to-noise ratio, high-resolution echelle spectroscopy. Internal uncertainties in the derived abundances are typically <~0.05dex. The stars in our sample have all been previously shown to have abundances that correlate with the condensation temperature (T_c_) of the elements in the sense of increasing abundances with increasing T_c_; these trends have been interpreted as evidence that the stars may have accreted H-depleted planetary material. Our newly derived abundances also correlate positively with T_c_, although slopes of linear least-square fits to the [m/H]-T_c_ relations for all but two stars are smaller here than in previous studies. When considering the refractory elements (T_c_>900K) only, which may be more sensitive to planet formation processes, the sample can be separated into a group with positive slopes (four stars) and a group with flat or negative slopes (six stars). The four stars with positive slopes have very close-in giant planets (three at 0.05AU) and slopes that fall above the general Galactic chemical evolution trend. We suggest that these stars have accreted refractory-rich planet material but not to the extent that would increase significantly the overall stellar metallicity. The flat or negative slopes of the remaining six stars are consistent with recent suggestions of a planet formation signature, although we show that the trends may be the result of Galactic chemical evolution.2011ApJ...732...55Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/732/55CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/539/A102 : HD 209458 and HD 189733 theoretical spectra (Hayek+, 2012)J/A+A/545/A32 : Chemical abundances of 1111 stars (Adibekyan+, 2012)J/MNRAS/414/1227 : Mg/Fe ratio of MILES stars (Milone+, 2011)J/A+A/523/A91 : CoRoT/Exoplanet fields with MATISSE (Gazzano+, 2010)J/ApJ/724/154 : Lithium abundances in stars with planets (Ghezzi+, 2010)J/ApJ/705/1226 : Planet-bearing stars in Spitzer (Bryden+, 2009)J/MNRAS/374/664 : Stellar parameters in MILES library (Cenarro+, 2007)J/AJ/131/2274 : TrES-1 equivalent widths (Sozzetti+, 2006)J/ApJ/646/505 : Catalog of nearby exoplanets (Butler+, 2006)J/PASJ/57/65 : CNO abundances of solar-type stars (Takeda+, 2005)J/A+A/438/139 : Abundances in Milky Way's disk (Soubiran+, 2005)J/AZh/82/453 : Spectroscopic abundances in stars (Borkova+, 2005)J/ApJS/161/444 : [Fe/H] and Teff for class IV-V stars (Taylor+, 2005)J/A+A/433/185 : Abundance analysis of 102 F and G dwarfs (Bensby+, 2005)J/A+A/423/677 : Abundances in chromospherically active stars (Morel+, 2004)J/A+A/415/155 : Oxygen abundances in the Galactic disk (Bensby+, 2004)J/MNRAS/325/1365 : Solar neighborhood metallicity distribution (Haywood+, 2001)J/A+A/356/590 : The CORALIE survey for extrasolar planets II (Udry+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/732/55https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/732/55http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/732/55https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/732/55https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/732/55http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/732/55GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/732/55/stars (Stellar carbon and oxygen abundances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/732/55/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/732/55/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/732/55/stars?GETtext/xml+votable180.050000true49.416855831.12704440.0055555555555555566/871 5718 6831 12644 12899 18821 22036 34951 37461 39257https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/732/55?format=asciidefaultJ/ApJ/732/55/starsStellar carbon and oxygen abundancesHDStar namemeta.id;meta.mainintprimaryrecnoRecord number assigned by the VizieR team.
