One of the most interesting correlations that has come out of large statistical studies of exoplanets is a relationship between the occurrence rate of giant planets and the metallicity of their host stars. The primary goal of this project is to develop an automated pipeline to measure stellar parameters (e.g. effective temperature, surface gravity and metallicity) of a large number of stars. We use a spectral index-based method that employs a Bayesian approach to determine the stellar parameters of stars. Results will be presented. This method will be applied to a large number of target stars in the Kepler field in order to determine the nature of the planet-metallicity correlation for small planets for the first time.
