Nine months of monitoring of a V777-Her pulsator with the Kepler spacecraft    [PDF]

The V777 Her pulsator KIC 8626021 has been observed continuously by the Kepler space telescope for nine months. Two new independent pulsation modes are detected in the extended dataset, which both match the predicted sequence of \ell = 2 modes. We demonstrate the photometric stability of the main pulsation modes and discuss the prospect of measuring period changes within the context of the extended Kepler mission.
