Regularities in frequency spacings of Delta Scuti stars: The Kepler star KIC 9700322
M. Breger, L. Balona, P. Lenz +15
In the faint star KIC 9700322 observed by the Kepler satellite, 76 frequencies with amplitudes from 14 to 29000 ppm were detected. The two dominant frequencies at 9.79 and 12.57 c/…
Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
M. D. Reed, S. L. Harms, S. Poindexter +58
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period just over two hours. The companion is most likely a w…
Atmospheric parameters and pulsational properties for a sample of \,Sct, \,Dor, and hybrid {\it Kepler} targets
G. Catanzaro, V. Ripepi, S. Bernabei +14
We report spectroscopic observations for 19 \,Sct candidates observed by the {\it Kepler} satellite both in long and short cadence mode. For all these stars, by using spectral s…
HAT-P-13: a multi-site campaign to detect the transit of the second planet in the system
Gy. M. Szabó, L. L. Kiss, J. M. Benkő +10
A possible transit of HAT-P-13c has been predicted to occur on 2010 April 28. Here we report on the results of a multi-site campaign that has been organised to detect the event. CC…
Flavours of variability: 29 RR Lyrae stars observed with Kepler
J. M. Benkő, K. Kolenberg, R. Szabó +18
We present our analysis of Kepler observations of 29 RR Lyrae stars, based on 138-d of observation. We report precise pulsation periods for all stars. Nine of these stars had incor…
Does Kepler unveil the mystery of the Blazhko effect? First detection of period doubling in Kepler Blazhko RR Lyrae stars
R. Szabó, Z. Kolláth, L. Molnár +15
The first detection of the period doubling phenomenon is reported in the Kepler RR Lyrae stars RR Lyr, V808 Cyg and V355 Lyr. Interestingly, all these pulsating stars show Blazhko…
Solar-like oscillations in cluster stars
D. Stello, S. Basu, T. R. Bedding +21
We present a brief overview of the history of attempts to obtain a clear detection of solar-like oscillations in cluster stars, and discuss the results on the first clear detection…
Ground-based follow-up in relation to Kepler Asteroseismic Investigation
K. Uytterhoeven, M. Briquet, H. Bruntt +12
The Kepler space mission, successfully launched in March 2009, is providing continuous, high-precision photometry of thousands of stars simultaneously. The uninterrupted time-serie…
First Kepler results on RR Lyrae stars
K. Kolenberg, R. Szabó, D. W. Kurtz +21
We present the first results of our analyses of selected RR Lyrae stars for which data have been obtained by the Kepler Mission. As expected, we find a significant fraction of the…
