Characterizing the Stellar-Metallicity versus Planet-Size Relation for Neptunian-Size Planets in the Kepler Data Release
Abstract
Chemical abundances in exoplanet hosting stars, in comparison to stars which do not harbor known planets, have been found to exhibit intriguing differences in their respective abundance distributions. These chemical signatures provide clues to how planets form, as well as how the parent star's properties affect the type of planetary system that forms. An accurate chemical abundance analysis conducted on a sample of Kepler transit systems will map these differences as a function of stellar mass and metallicity, planet size, and orbital period.
