MOST photometry of the enigmatic PMS pulsator HD 142666
K. Zwintz, T. Kallinger, D. B. Guenther +11
We present precise photometry of the pulsating Herbig Ae star HD 142666 obtained in two consecutive years with the MOST (Microvariability & Oscilations of STars) satellite. Previou…
The nature of p-modes and granulation in HD 49933 observed by CoRoT
T. Kallinger, M. Gruberbauer, D. B. Guenther +2
Context: Recent observations of HD49933 by the space-photometric mission CoRoT provide photometric evidence of solar type oscillations in a star other than our Sun. The first publi…
Oscillating red giants in the CoRoT exo-field: Asteroseismic mass and radius determination
T. Kallinger, W. W. Weiss, C. Barban +10
Context. Observations and analysis of solar-type oscillations in red-giant stars is an emerging aspect of asteroseismic analysis with a number of open questions yet to be explored.…
On the detection of Lorentzian profiles in a power spectrum: A Bayesian approach using ignorance priors
M. Gruberbauer, T. Kallinger, W. W. Weiss +1
Aims. Deriving accurate frequencies, amplitudes, and mode lifetimes from stochastically driven pulsation is challenging, more so, if one demands that realistic error estimates be g…
Solar-like oscillations in red giants in the CoRoT exo-field
S. Hekker, C. Barban, T. Kallinger +4
Asteroseismic observations from space can provide us with long time series of uninterrupted high quality data for many stars at the same time. The CoRoT satellite (Convection Rotat…
MOST photometry of the roAp star 10 Aql
D. Huber, H. Saio, M. Gruberbauer +12
Context: We present 31.2 days of nearly continuous MOST photometry of the roAp star 10Aql. Aims:The goal was to provide an unambiguous frequency identification for this little stud…
