cds-question@unistra.frchemical-abundancesdwarf-starsHost star metallicities have been used to infer observational constraints on planet formation throughout the history of the exoplanet field. The giant planet metallicity correlation has now been widely accepted, but questions remain as to whether the metallicity correlation extends to the small terrestrial-sized planets. Here, we report metallicities for a sample of 518 stars in the Kepler field that have no detected transiting planets and compare their metallicity distribution to a sample of stars that hosts small planets (Rp<1.7R_{Earth}_). Importantly, both samples have been analyzed in a homogeneous manner using the same set of tools (Stellar Parameters Classification tool). We find the average metallicity of the sample of stars without detected transiting planets to be [m/H]_SNTP,dwarf_=-0.02+/-0.02dex and the sample of stars hosting small planets to be [m/H]_STP_=-0.02+/-0.02dex. The average metallicities of the two samples are indistinguishable within the uncertainties, and the two-sample Kolmogorov-Smirnov test yields a p-value of 0.68 (0.41{sigma}), indicating a failure to reject the null hypothesis that the two samples are drawn from the same parent population. We conclude that the homogeneous analysis of the data presented here supports the hypothesis that stars hosting small planets have a metallicity similar to stars with no known transiting planets in the same area of the sky.2015ApJ...808..187Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/808/187CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/ApJS/210/1 : Asteroseismic study of solar-type stars (Chaplin+, 2014)J/ApJ/771/107 : Spectroscopy of faint KOI stars (Everett+, 2013)J/ApJ/767/95 : Improved parameters of smallest KIC stars (Dressing+, 2013)J/A+A/551/A36 : Metallicity of M dwarfs.
