Asteroseismology of red giants from the first four months of Kepler data: Fundamental parameters
red giants from Kepler data Fundamental parameters
2011/1/10
Clear power excess in a frequency range typical for solar-type oscillations in red giants has been detected in more than 1000 stars, which have been observed during the first 138 days of the science o...
Asteroseismology of red giants from the first four months of Kepler data: Global oscillation parameters for 800 stars
Asteroseismology red giants the first four months
2011/1/10
We have studied solar-like oscillations in ~800 red-giant stars using Kepler long-cadence photometry. The sample includes stars ranging in evolution from the lower part of the red-giant branch to the ...
Observational asteroseismology of hot subdwarf stars
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
Hot subdwarf stars are particularly challenging for asteroseismology due to their rapid pulsation periods, intrinsic faintness and relative rarity both in the field and in clusters. These features hav...
On the Analysis of Light Curves in Asteroseismology
Fourier analysis noise sources ill-posed problems
2009/5/12
We provide a detailed introduction to the main problems arising
when analyzing light curves in asteroseismology. Attention is first paid to
the signal model delivered by the pulsating stars and to t...
