  • 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 ...

  • Uytterhoeven, K.; Moya, A.; Grigahcene, A.; Guzik, J. A.; Gutierrez-Soto, J.; Smalley, B.; Handler, G.; Balona, L. A.; Niemczura, E.; Fox Machado, L.; Gruberbauer, Michael (EDP Sciences, 2011-10)
    Context. The Kepler spacecraft is providing time series of photometric data with micromagnitude precision for hundreds of A-F type stars. Aims. We present a first general characterization of the pulsational behaviour of ...

  • 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. ...

  • 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] ...
