Title: Using Chemical Abundance Signatures in Kepler-Field Solar-Twins to Infer the Existence of Inner Rocky-Planet Architectures

Abstract: This proposal will target a sample of Kepler small-planet candidate systems with high-resolution spectroscopy in order to perform the requisite precision abundance analyses (at the 0.02 to 0.03 dex level) to test the hypothesis that inner rocky-planetary systems reveal themselves through chemical abundance patterns in their parent stars. These patterns consist of relative abundances between volatile and refractory elements. Small inner-planetary systems identified by Kepler are the only objects that can provide the definitive test of this potentially important, but still unproven effect, as evidenced by a recent controversy in the literature.
