Kepler photometry of RRc stars: peculiar double-mode pulsations and period doubling
P. Moskalik, R. Smolec, K. Kolenberg +11
We present the analysis of four first overtone RR Lyrae stars observed with the Kepler space telescope, based on data obtained over nearly 2.5yr. All four stars are found to be mul…
Connection between the period and the amplitude of the Blazhko effect
J. M. Benkő, R. Szabó
We found a possible relationship between the modulation period and the amplitude of the Blazhko RR Lyrae stars: long modulation period generally implies high modulation amplitude w…
The space photometry revolution and our understanding of RR Lyrae stars
R. Szabó, J. M. Benkő, M. Paparó +7
The study of RR Lyrae stars has recently been invigorated thanks to the long, uninterrupted, ultra-precise time series data provided by the Kepler and CoRoT space telescopes. We gi…
Nonlinear dynamical analysis of the Blazhko effect with the Kepler space telescope: the case of V783 Cyg
E. Plachy, J. M. Benkő, Z. Kolláth +2
We present a detailed nonlinear dynamical investigation of the Blazhko modulation of the Kepler RR Lyrae star V783 Cyg (KIC 5559631). We used different techniques to produce modula…
HD 183648: a Kepler eclipsing binary with anomalous ellipsoidal variations and a pulsating component
T. Borkovits, A. Derekas, J. Fuller +16
KIC 8560861 (HD 183648) is a marginally eccentric (e=0.05) eclipsing binary with an orbital period of P_orb=31.973d, exhibiting mmag amplitude pulsations on time scales of a few da…
Long time-scale behavior of the Blazhko effect from rectified Kepler data
J. M. Benkő, E. Plachy, R. Szabó +2
In order to benefit from the 4-year unprecedented precision of the Kepler data, we extracted light curves from the pixel photometric data of the Kepler space telescope for 15 Blazh…
Cepheids and RR Lyrae stars in the K2 fields
L. Molnár, E. Plachy, R. Szabó
With the step-and-stare approach of the K2 mission, Kepler will be able to observe a large number of Cepheid an RR Lyrae stars. In this paper we describe the target selection effor…
The historical vanishing of the Blazhko effect of RR Lyr from GEOS and Kepler surveys
J. F. Le Borgne, E. Poretti, A. Klotz +20
RR Lyr is one of the most studied variable stars. Its light curve has been regularly monitored since the discovery of the periodic variability in 1899. Analysis of all observed max…
