The Kepler spacecraft is monitoring the brightness of more than 150,000 stars in the constellations Cygnus, Lyra, and Draco. The photometric time series with micromagnitude precision are excellent for the study of stellar oscillations. The oscillations lead to small changes in brightness and are caused by waves trapped inside the stars. The field of asteroseismology uses information from the stellar oscillations to infer information from the stellar internal structure. The delta Scuti and gamma Doradus stars are two classes of oscillating stars of spectral type A and F that are slightly
