Description
CoRoT and Kepler high-precision photometric data allowed the detection
and characterization of the oscillation parameters in stars other than
the Sun. Moreover, thanks to the scaling relations, it is possible to
estimate masses and radii for thousands of solar-type oscillating stars.
Recently, a Δν - ρ relation has been found for δ
Scuti stars. Now, analysing several hundreds of this kind of stars
observed with CoRoT and Kepler, we present an empiric relation between
their frequency at maximum power of their oscillation spectra and their
effective temperature. Such a relation can be explained with the help of
the κ-mechanism and the observed dispersion of the residuals is
compatible with they being caused by the gravity-darkening effect.

The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary
