refine existing methods for analysis of the asteroseismic data on Sun-like stars and to develop new ones. The asteroFLAG group is diverse. There is expertise from those involved in the cutting-edge ground-based asteroseismic observations; members of the CoRoT Data Analysis Team (DAT) (see Appourchaux 2003; 2006a, b); members of the Kepler Asteroseismology Science Consortium (KASC) (Christensen-Dalsgaard et al. 2007); leading theoreticians on the interior structures of stars and Sun-like oscillations; and those involved in the analysis of the so-called “Sun-as-a-star” helioseismology data, for which the analysis methods have direct application to the asteroseismic case (e.g., Chaplin et al. 2006).

The input data for probing stellar interiors are the mode parameters, such as individual frequencies, frequency splittings, linewidths and powers. For those stars where measurement of individual mode parameters is difficult, the input data will be the likes of average frequency spacings. Accurate mode parameter data are a vital prerequisite for robust, accurate inference on the internal structures of the stars. Our objectives are to test aspects of the complete analysis pipelines for stars, i.e., extraction of estimates of the mode parameters from observations, through to procedures used to draw inference on the fundamental stellar properties and the internal structures.
