First Kepler results on compact pulsators II: KIC 010139564, a new pulsating subdwarf B (V361 Hya) star with an additional low-frequency mode
Steven D. Kawaler, M. D. Reed, A. C. Quint +13
We present the discovery of nonradial pulsations in a hot subdwarf B star based on 30.5 days of nearly continuous time-series photometry using the \emph{Kepler} spacecraft. KIC 010…
First Kepler results on compact pulsators III: Subdwarf B stars with V1093~Her and hybrid (DW~Lyn) type pulsations
M. D. Reed, S. D. Kawaler, R. H. Ostensen +12
We present the discovery of nonradial pulsations in five hot subdwarf B (sdB) stars based on 27 days of nearly continuous time-series photometry using the Kepler spacecraft. We fin…
First Kepler results on compact pulsators V: Slowly pulsating subdwarf B stars in short-period binaries
S. D. Kawaler, M. D. Reed, R. H. Østensen +15
The survey phase of the Kepler Mission includes a number of hot subdwarf B (sdB) stars to search for nonradial pulsations. We present our analysis of two sdB stars that are found t…
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…
First Kepler results on compact pulsators I. Survey target selection and the first pulsators
R. H. Østensen, R. Silvotti, S. Charpinet +25
We present results from the first two quarters of a survey to search for pulsations in compact stellar objects with the Kepler spacecraft. The survey sample and the various methods…
