    The first evidence for multiple pulsation axes: a new rapidly oscillating Ap star in the Kepler field, KIC 10195926 
    Gruberbauer, Michael; Kurtz, D. W.; Cunha, M. S.; Saio, H.; Bigot, L.; Balona, L. A.; Elkin, V. G.; Shibahashi, H.; Brandao, I. M.; Uytterhoeven, K. (Royal Astronomical Society, 2011-07-01)
    We have discovered a new rapidly oscillating Ap (roAp) star among the Kepler mission target stars, KIC 10195926. This star shows two pulsation modes with periods that are amongst the longest known for roAp stars at 17.1 ...

    Kepler observations of rapidly oscillating Ap, [delta] Scuti and [gamma] Doradus pulsations in Ap stars 
    Balona, L. A.; Cunha, M. S.; Kurtz, D. W.; Brandao, I. M.; Gruberbauer, Michael; Saio, H.; Ostensen, R.; Elkin, V. G.; Borucki, W. J.; Christensen-Dalsgaard, J. (Wiley-Blackwell, 2011-01-01)
    Observations of the A5p star KIC 8677585 obtained during the Kepler 10-d commissioning run with 1-min time resolution show that it is a rapidly oscillating Ap (roAp) star with several frequencies with periods near 10 min. ...

    Rotation and oblique pulsation in Kepler observations of the roAp star KIC 10483436 
    Gruberbauer, Michael; Balona, L. A.; Cunha, M. S.; Kurtz, D. W.; Saio, H.; White, T. R.; Christensen-Dalsgaard, J.; Kjeldsen, H.; Christiansen, J. L.; Hall, J. R. (Oxford University Press, 2011)
    Photometry of KIC 10483436 was obtained continuously with 1-min exposures over a 27-d period from the Kepler satellite. The light curve shows rotational variations from surface spots with a period of 4.303 [plus or minus] ...
