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…
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…
Stellar origin of the 182Hf cosmochronometer and the presolar history of solar system matter
Maria Lugaro, Alexander Heger, Dean Osrin +7
Among the short-lived radioactive nuclei inferred to be present in the early solar system via meteoritic analyses, there are several heavier than iron whose stellar origin has been…
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…
Origin of Anomalous Xe-H in Nanodiamond Stardust
K. -L. Kratz, K. Farouqi, O. Hallmann +2
Still today, the nucleosynthesis origin of Xe-H in presolar nanodiamonds is far from understood. Historically, possible explanations were proposed by a secondary "neutron-burst" pr…
V473 Lyrae, a unique second-overtone Cepheid with two modulation cycles
László Molnár, László Szabados
V473 Lyrae is the only Galactic Cepheid with confirmed periodic amplitude and phase variations similar to the Blazhko effect observed in RR Lyrae stars. We collected all available…
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.
