Title: Spectroscopy of Kepler Exo-planet Transit Candidate Stars

Abstract: We propose a long term spectroscopic follow-up program in support of the NASA Kepler exo-planet mission. The Kepler project is now focusing on exo-planet candidates which are smaller in radius (down to Earth- size), have longer period orbits, and exo-planet candidates around fainter stars and eclipsing binary stars. We have five scientific goals for this project: 1) obtain reconnaissance type spectra for newly discovered exo-planet stars leading to model fits for Teff and log g, 2) provide radial velocity solutions for eclipsing binary star systems in which a third body exo-planet candidate has been detected, 3) Provide velocity or line asymmetry (bisector) measurements in order to provide a line of defense against unseen stellar mass companions, 4) obtain good S/N spectroscopic observations of new white dwarfs to use as photometric calibrators for the Kepler focal plane, and 5) obtain spectra of odd/interesting variable stars discovered by Kepler. All of these tasks can be accomplished using the Kitt Peak 4-m telescope and RCSPEC as shown by our previous time allocation.
