Title: Planet Occurrence around Mid-Type M Dwarfs in the Kepler Field

Abstract: The planet occurrence rate increases with decreasing stellar mass (later spectral types); therefore, M dwarf systems are our most promising targets in the search for exoplanets. The identification and characterization of stars in the original Kepler field was accomplished using photometry alone resulting in large uncertainties for late-type stars like M dwarfs. In order to more accurately compute the planet occurrence rate around mid-type M dwarfs, we need to better constrain their stellar radii and masses, properties which strongly correlate with other stellar parameters such as temperature and metallicity. These measurements need to be performed on a statistically significant population of stars including systems with and without planets. it{Therefore, we seek to fully spectroscopically characterize the properties of probable mid-type M dwarfs in the Kepler field using red optical spectra obtained with Hydra on WIYN in order to constrain the planet occurrence rate for such stars.}
