Model fitting by phase matching - theory and application to CoRoT and Kepler stars
We show that the inner phase shifts, the departure of the eigenmodes froma simple harmonic function. of model stars collapse to a single l independent function of frequency in the outer layers of the star. We then show how to find a best fit model to an observed frequency set by calculating the inner phase shifts using the observed frequencies and determining the extent to which these collapse to a single function of frequency in the outer layers of the model. We apply this technique to find models of some stars observed by CoRoT and Kepler
