Internal mixing of rotating stars inferred from dipole gravity modes
May G. Pedersen, Conny Aerts, Péter I. Pápics +7
During most of their life, stars fuse hydrogen into helium in their cores. The mixing of chemical elements in the radiative envelope of stars with a convective core is able to repl…
Wandering near the red edge: photometric observations of three cool ZZ Ceti stars
Zs. Bognár, M. Paparó, Á. Sódor +11
We summarize our findings on three cool ZZ Ceti type pulsating white dwarfs. We determined eight independent modes in HS 0733+4119, of which seven are new findings. For GD 154, we…
Search for exoplanets around pulsating stars of A--F type in Kepler Short Cadence data and the case of KIC 8197761
Paulina Sowicka, Gerald Handler, Bartłomiej Dębski +3
We searched for extrasolar planets around pulsating stars by examining data for transit-like events hidden in the intrinsic variability. All Short Cadence observa…
Detection of Solar-Like Oscillations, Observational Constraints, and Stellar Models for Cyg, the Brightest Star Observed by the {\it Kepler} Mission
J. A. Guzik, G. Houdek, W. J. Chaplin +52
Cygni is an F3 spectral-type main-sequence star with visual magnitude V=4.48. This star was the brightest star observed by the original Kepler spacecraft mission. Short-cadence…
Asteroseismic fingerprints of rotation and mixing in the slowly pulsating B8 V star KIC 7760680
P. I. Pápics, A. Tkachenko, C. Aerts +5
We present the first detection of a rotationally affected series consisting of 36 consecutive high-order sectoral dipole gravity modes in a slowly pulsating B (SPB) star. The resul…
Detection of solar-like oscillations in the bright red giant stars Psc and Tau from a 190-day high-precision spectroscopic multisite campaign
P. G. Beck, E. Kambe, M. Hillen +35
Red giants are evolved stars which exhibit solar-like oscillations. Although a multitude of stars have been observed with space telescopes, only a handful of red-giant stars were t…
Pulsating red giant stars in eccentric binary systems discovered from Kepler space-based photometry
P. G. Beck, K. Hambleton, J. Vos +30
The unparalleled photometric data obtained by NASA's Kepler space telescope led to an improved understanding of red giant stars and binary stars. Seismology allows us to constrain…
The CoRoT B-type binary HD50230: a prototypical hybrid pulsator with g-mode period and p-mode frequency spacings
P. Degroote, C. Aerts, E. Michel +14
B-type stars are promising targets for asteroseismic modelling, since their frequency spectrum is relatively simple. We deduce and summarise observational constraints for the hybri…
CoRoT high-precision photometry of the B0.5 IV star HD 51756
P. I. Pápics, M. Briquet, M. Auvergne +13
OB stars are important constituents for the ecology of the Universe, and there are only a few studies on their pulsational properties detailed enough to provide important feedback…
The tip of the iceberg: the frequency content of the Delta Sct star HD 50844 from CoRoT space photometry
E. Poretti, L. Mantegazza, M. Rainer +19
It has been suggested that the detection of a wealth of very low amplitude modes in Delta Sct stars was only a matter of signal--to--noise ratio. Access to this treasure, impossibl…
More frequencies of KUV 02464+3239
Zs. Bognár, M. Paparó, A. Már +6
Preliminary results on KUV 02464+3239, a pulsating DA white dwarf are presented. Located near the red edge of the DAV instability strip, KUV 02464+3239 shows large amplitude and lo…
