Asteroseismology of the Transiting Exoplanet Host HD 17156 with HST FGS
planetary systems stars oscillations stars individual techniques
2010/11/9
Observations conducted with the Fine Guidance Sensor on Hubble Space Telescope (HST) providing
high cadence and precision time-series photometry were obtained over 10 consecutive days in December 200...
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...
Lessons for Asteroseismology from White Dwarf Stars

2009/5/12
The interpretation of pulsation data for sun-like stars is
currently facing challenges quite similar to those faced by white dwarf
modelers ten years ago. The observational requirements for uninterr...
Asteroseismology of δ Scuti Stars：Problems and Prospects
δ Scuti stars pre-main sequence stars
2009/5/12
We briefly outline the state-of-the-art seismology of δ Scuti
stars from a theoretical point of view: why is it so difficult a task? The recent
theoretical advances in the field that these difficult...
We give an overview of past and present efforts to make seismology
of δ Scuti and γ Doradus stars possible. Previous work has not
led to the observational detection and identification of a sufficien...
The increasing number of pulsating modes in a star leads to the
increase of the amount of information derived from the pulsation. Probing
the invisible interior of stars is a dream come true. In thi...
Asteroseismology：Past, Present and Future
Asteroseismology stellar pulsation variable stars
2009/5/12
Asteroseismology studies stars with a wide variety of interior
and surface conditions. For two decades asteroseismic techniques have
been applied to many pulsating stars across the HR diagram. Aster...
