Metallicity Analysis of Kepler-65, Kepler-93, Kepler-99, Kepler-102, Kepler-406, and Kepler-409
Abstract
This study aims to examine the influence stellar metallicity may have on planet formation in various exoplanet systems discovered by NASA's Kepler spacecraft. We have analyzed Keck/HIRES spectra of the planetary hosts Kepler-65, Kepler-93, Kepler-99, Kepler-102, Kepler-406, and Kepler-409 systems and derived the abundances of 17 elements for these stars. Results from previous studies have suggested that stellar abundance patterns or 'signatures' may indicate the presence of planets, possibly terrestrial planets in particular, and thus such patterns may be used to identify stars with planets, including potentially Earth-like terrestrial planets. Here we present the results of our abundance analysis of 6 stars with a variety of exoplanet systems discovered by Kepler.
