Abstract: The V = 4.48 F4 main-sequence star θ Cyg is the brightest star observable in the Kepler spacecraft field of view. Short-cadence (58.8 s) photometric data were obtained by Kepler during June–September 2010. Preliminary analysis shows solar-like oscillations in the frequency range 1200– 2500 μHz. To interpret these data and to motivate further observations, we use observational constraints from the literature to construct stellar evolution and pulsation models for this star. We compare the observed large frequency separation of the solar-like oscillations with the model predictions and discuss the prospects for γ Doradus-like g-mode pulsations, given the observational constraints. We discuss the value of angular diameter measurements from optical interferometry for constraining stellar properties and the implications for asteroseismology.
