Abstract

We present preliminary results based on the CoRoT observations
of the young distant cluster Dolidze 25. The light curve for the 28 stars
observed by the satellite are analyzed and the relevant periodogram presented.
The physical parameters for a subsample of stars for which we possess AAOMEGA and FLAMES@VLT spectra are also reported. In total, we have identified 2 binary, 3 Pulsating Be, 3 SPB, 2 Spotted, 1 ellipsoidal, and 1 $\delta$ Scuti variables. The membership of these variables to Dolidze 25 is discussed.
