Kepler Asteroseismology Program: Introduction and First Results
Ronald L. Gilliland, T. M. Brown, J. Christensen-Dalsgaard +32
Asteroseismology involves probing the interiors of stars and quantifying their global properties, such as radius and age, through observationsof normal modes of oscillation. The te…
Detection of solar-like oscillations from Kepler photometry of the open cluster NGC 6819
Dennis Stello, Sarbani Basu, Hans Bruntt +49
Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance and initial chemical composition allows strong tests of the theor…
Determination of stellar radii from asteroseismic Data
Sarbani Basu, William J. Chaplin, Yvonne Elsworth
The NASA Kepler mission is designed to find planets through transits. Accurate and precise radii of the detected planets depend on knowing the radius of the host star accurately, w…
Is the current lack of solar activity only skin deep?
A. -M. Broomhall, W. J. Chaplin, Y. Elsworth +2
The Sun is a variable star whose magnetic activity and total irradiance vary on a timescale of approximately 11 years. The current activity minimum has attracted considerable inter…
Solar-like oscillations with low amplitude in the CoRoT target HD 181906
R. A. Garcia, C. Regulo, R. Samadi +23
Context: The F8 star HD 181906 (effective temperature ~6300K) was observed for 156 days by the CoRoT satellite during the first long run in the centre direction. Analysis of the da…
Mode lifetimes of stellar oscillations - Implications for asteroseismology
W. J. Chaplin, G. Houdek, C. Karoff +2
Successful inference from asteroseismology relies on at least two things: that the oscillations in the stars have amplitudes large enough to be clearly observable; and that the osc…
