Asteroseismology of CoRoT & Kepler delta Scuti stars

Asteroseismology allow us to probe the physical conditions inside the stars using the stellar power spectra. Using our own methodology and taking advantage of CoRoT and Kepler light curves, we analyze the power spectral structure of delta Scuti stars including the lowest amplitude modes. In that way, we have been able to estimate the stellar parameters of four delta Scuti stars, allowing us to explain their spectral structure. In addition, studying a larger sample of these kind of stars, we find a possible scaling relation and we observe that most part of the mode variations might be caused by resonant mode coupling.
