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 ...
Toward a new kind of asteroseismic grid fitting

Gruberbauer, Michael; Guenther, David B.; Kallinger, T. (American Astronomical Society, 2012-04-20)

Recent developments in instrumentation (e.g., in particular the Kepler and CoRoT satellites) provide a new opportunity to improve the models of stellar pulsations. Surface layers, rotation, and magnetic fields imprint ...
