Abstract:
The presence of g- and p-modes allows testing stellar models from the
core to the envelope. Moreover, binarity in an eclipsing system
constrains the physical parameters of the pulsating star.
CoRot ID 100866999 is a relatively large-amplitude hybrid
gamma Doradus-delta Scuti star with two clearly distinct frequency
domains. The large number of detected frequencies allows a detailed
study of the interaction between them. In addition, we can derive the
fundamental parameters of both components from the study of the
eclipsing light curve.
After removing the eclipsing phases, we analyzed the data with the
Period04 package up to a signal-to-noise ratio S/N=4. The light
curve was then prewhitened with these oscillation frequencies to
derive the fundamental parameters of the two components.
