Title: Stellar Parameters for Pulsating B Star Candidates in the Kepler Field

Abstract: The advent of recent missions such as \textitKepler that provide wide-field, high-precision photometry is renewing interest in asteroseismology for a broad set of applications in stellar astrophysics. This wealth of new data can potentially allow observers to determine fundamental stellar properties and improve stellar structure and evolution models for a range of spectral types. Recently, 85 candidate (beta) Cep, SPB, and hybrid pulsating B stars have been identified in the \textitKepler field, but most of them have unknown physical parameters that are necessary to calibrate asteroseismic models. Here we propose to use the KPNO 4m telescope + RC spectrograph to measure precise values of T_\rm eff, \log g, and V \sin i for these pulsating B-type candidates in the \textitKepler field. Our measurements will greatly enhance the asteroseismic value of that dataset.
