V473 Lyr, a modulated, period-doubled Cepheid, and U TrA, a double-mode Cepheid observed by MOST
L. Molnár, A. Derekas, R. Szabó +36
Space-based photometric measurements first revealed low-amplitude irregularities in the pulsations of Cepheid stars, but their origins and how commonly they occur remain uncertain.…
White Dwarf Period Tables - I. Pulsators with hydrogen-dominated atmospheres
Zs. Bognár, Á. Sódor
We aimed at collecting all known white dwarf pulsators with hydrogen-dominated atmospheres and list their main photometric and atmospheric parameters together with their pulsation…
KIC 2831097 - A 2-year orbital-period RR Lyrae binary candidate
Á. Sódor, M. Skarka, J. Liška +1
We report the discovery of a new Kepler first-overtone RR Lyrae pulsator, KIC 2831097. The pulsation shows large, 0.1 d amplitude, systematic phase variations that can be interpret…
The discovery of a planetary candidate around the evolved low-mass Kepler giant star HD 175370
M. Hrudková, A. Hatzes, R. Karjalainen +20
We report on the discovery of a planetary companion candidate with a minimum mass Msini = 4.6 M_J orbiting the K2 III giant star HD 175370 (KIC 007940959). This star was a target i…
The Kepler Cepheid V1154 Cyg revisited: light curve modulation and detection of granulation
A. Derekas, E. Plachy, L. Molnar +8
We present a detailed analysis of the bright Cepheid-type variable star V1154 Cygni using 4 years of continuous observations by the Kepler space telescope. We detected 28 frequenci…
Finest light curve details, physical parameters, and period fluctuations of CoRoT RR Lyrae stars
J. M. Benkő, R. Szabó, A. Derekas +1
The CoRoT satellite supplied the scientific community with a huge data base of variable stars. Among them the RR Lyrae stars have intensively been discussed in numerous papers in t…
