Study of the young open cluster IC2391: discovery of X-ray rotational modulation in a supersaturated star
Abstract
We present the analysis of the Guarantee Time XMM-Newton/EPIC observation pointed on the young open cluster IC 2391. We find evidence, for the first time, of X-ray rotational modulation on a supersaturated star, member of the cluster, implying the presence of structural inhomogeneities. We also present preliminary results of the spectral analysis of the X-ray brightest cluster stars.
