  The mass of the planet-hosting giant star [beta] Geminorum determined from its p-mode oscillation spectrum 

  Guenther, David B.; Hatzes, A. P.; Zechmeister, M.; Matthews, J.; Kuschnig, R.; Walker, G. A. H.; Dollinger, M.; Moffat, A. F. J.; Rucinski, S. M.; Sasselov, D. (European Southern Observatory, 2012)

  Aims. Our aim is to use precise radial velocity measurements and photometric data to derive the frequency spacing of the p-mode oscillation spectrum of the planet-hosting star [beta] Gem. This spacing along with the ...

  MOST observations of the roAp stars HD 9289, HD 99563, and HD 134214 

  Guenther, David B.; Gruberbauer, Michael; Huber, D.; Kuschnig, R.; Weiss, W. W.; Matthews, J. M.; Moffat, A. F. J.; Rowe, J. F.; Rucinski, S. M.; Sasselov, D. (EDP Sciences, 2011-06)

  We report on the analysis of high-precision space-based photometry of the roAp (rapidly oscillating Ap) stars HD 9289, HD 99563, and HD 134214. All three stars were observed by the MOST satellite for more than 25 days, ...

  A search for p-modes and other variability in the binary system 85 Pegasi using MOST photometry 

  Guenther, David B.; Gruberbauer, Michael; Huber, D.; Matthews, J. M.; Croll, B.; Obbrugger, M.; Weiss, W. W.; Rowe, J. F.; Kallinger, T.; Kuschnig, R. (EDP Sciences, 2009-10)

  Context. Asteroseismology has great potential for the study of metal-poor stars due to its sensitivity to determine stellar ages. Solid detections of oscillation frequencies in stars with well constrained fundamental ...

  CINDERELLA: comparison of INDEpendent RELative least-squares amplitudes 

  Gruberbauer, Michael; Reegen, P.; Schneider, L.; Weiss, W. W. (EDP Sciences, 2008-06)

  Context. The identification of smaller and smaller signals from objects observed with a non-perfect instrument in a noisy environment poses a challenge for a statistically clean data analysis. Aims. We compute the probability ...

  On the detection of Lorentzian profiles in a power spectrum: a Bayesian approach using ignorance priors 

  Guenther, David B.; Gruberbauer, Michael; Kallinger, T.; Weiss, W. W. (EDP Sciences, 2009-11)

  Aims. Deriving accurate frequencies, amplitudes, and mode lifetimes from stochastically driven pulsation is challenging, more so, if one demands that realistic error estimates be given for all model fitting parameters. As ...
