Period doubling in Kepler RR Lyrae stars
R. Szabó, Z. Kolláth, L. Molnár +3
The origin of the conspicuous amplitude and phase modulation of the RR Lyrae pulsation - known as the Blazhko effect - is still a mystery after more than 100 years of its discovery…
Ground-Based BVRI Follow-Up Observations of the Cepheid V1154 Cyg in Kepler's Field
C. -C. Ngeow, R. Szabo, L. Szabados +3
The almost un-interrupted observations from Kepler Space Telescope can be used to search for Earth-size and larger planets around other stars, as well as for stellar variability an…
Non-Blazhko RR Lyrae Stars Observed with the KEPLER Space Telescope
J. M. Nemec, R. Smolec, J. M. Benko +22
This paper summarizes the main results of our recent study of the non-Blazhko RR Lyrae stars observed with the Kepler space telescope. These stars offer the opportunity for studyin…
Fourier analysis of non-Blazhko ab-type RR Lyrae stars observed with the Kepler space telescope
J. M. Nemec, R. Smolec, J. M. Benko +22
Nineteen of the ~40 RR Lyr stars in the Kepler field have been identified as candidate non-Blazhko (or unmodulated) stars. In this paper we present the results of Fourier decomposi…
Blazhko RR Lyrae light curves as modulated signals
J. M. Benkő, R. Szabó, M. Paparó
We present an analytical formalism for the description of Blazhko RR Lyrae light curves in which employ a treatment for the amplitude and frequency modulations in a manner similar…
Asteroseismic inferences on red giants in open clusters NGC 6791, NGC 6819 and NGC 6811 using Kepler
S. Hekker, S. Basu, D. Stello +17
Context: Four open clusters are present in the Kepler field of view and timeseries of nearly a year in length are now available. These timeseries allow us to derive asteroseismic g…
Kepler observations of variability in B-type stars
L. A. Balona, A. Pigulski, P. De Cat +27
The analysis of the light curves of 48 B-type stars observed by Kepler is presented. Among these are 15 pulsating stars, all of which show low frequencies characteristic of SPB sta…
Period doubling bifurcation and high-order resonances in RR Lyrae hydrodynamical models
Z. Kolláth, L. Molnár, R. Szabó
We investigated period doubling, a well-known phenomenon in dynamical systems, for the first time in RR Lyrae models. These studies provide theoretical background for the recent di…
Cepheid investigations using the Kepler space telescope
R. Szabó, L. Szabados, C. -C. Ngeow +35
We report results of initial work done on selected candidate Cepheids to be observed with the Kepler space telescope. Prior to the launch 40 candidates were selected from previous…
