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…
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…
On the interchange of alternating-amplitude pulsation cycles
E. Plachy, L. Molnár, Z. Kolláth +2
We characterized the time intervals between the interchanges of the alternating high- and low-amplitude extrema of three RV Tauri and three RR Lyrae stars.
