Abstract

P modes observed in Red Giants are acoustic resonances similar to those
observed in the Sun, stochastically excited by turbulent convection.

The high-quality and quasi-uninterrupted space data obtained by CoRoT allow us
to make a big step forward in the study of such oscillations in Red Giants by
increasing significantly the number of stars for which such oscillations
can be detected.

We present here the data analysis of a sample of Red Giants observed during
the first long Run of CoRoT (142 days). Detailed p-modes properties are
estimated with a particular emphasis on the frequency spacings.
