Observations from the Kepler satellite were recently published for threebright G-type stars, which were monitored during the first 33.5d of scienceoperations. One of these stars, KIC 11026764, exhibits a characteristic patternof oscillation frequencies suggesting that the star has evolved significantly.We have derived initial estimates of the properties of KIC 11026764 from theoscillation frequencies observed by Kepler, combined with ground-basedspectroscopic data. We present preliminary results from detailed modeling ofthis star, employing a variety of independent codes and analyses that attemptto match the asteroseismic and spectroscopic constraints simultaneously.
