Carbon and oxygen abundances in FGK stars J/ApJ/735/41 ivo://CDS.VizieR/J/ApJ/735/41 doi:10.26093/cds/vizier.17350041 CDS Petigura E.A. Marcy G.W. 2017-11-29T11:49:08Z 2013-01-16T09:19:14Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr chemical-abundances late-type-stars spectroscopy We present carbon and oxygen abundances for 941 FGK stars -the largest such catalog to date. We find that planet-bearing systems are enriched in these elements. We self-consistently measure N_C_/N_O_, which is thought to play a key role in planet formation. We identify 46 stars with N_C_/N_O_>=1.00 as potential hosts of carbon-dominated exoplanets. We measure a downward trend in [O/Fe] versus [Fe/H] and find distinct trends in the thin and thick disks, supporting the work of Bensby et al. Finally, we measure sub-solar N_C_/N_O_=0.40^+0.11^_-0.07_, for WASP-12, a surprising result as this star is host to a transiting hot Jupiter whose dayside atmosphere was recently reported to have N_C_/N_O_>=1 by Madhusudhan et al. Our measurements are based on 15,000 high signal-to-noise spectra taken with the Keck 1 telescope as part of the California Planet Search. We derive abundances from the [OI] and CI absorption lines at {lambda}=6300 and 6587{AA} using the SME spectral synthesizer. 2011ApJ...735...41P https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/735/41 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to I/239 : The Hipparcos and Tycho Catalogues (ESA 1997) J/A+A/547/A106 : Li abundances in the FGK dwarfs (Mishenina+, 2012) J/A+A/533/A141 : Stellar parameters for 582 HARPS FGK stars (Sousa+, 2011) J/A+A/526/A71 : C abundances in G and K nearby stars (Da Silva+, 2011) J/A+A/465/271 : Oxygen abundances in nearby stars (Ramirez+, 2007) J/ApJS/168/297 : Stellar parameters of nearby cool stars (Takeda+, 2007) J/AJ/129/1063 : Abundances of stars within 15pc of the Sun (Luck+, 2005) J/PASJ/57/65 : CNO abundances of solar-type stars (Takeda+, 2005) J/ApJS/159/141 : Spectroscopic properties of cool stars.
