CORONAL EMISSION FROM SUPERSATURATED STARS

We propose to observe two young fast rotating stars observed with ROSAT in thesupersaturation regime. We aim at detecting rotational modulation in their Xrayemission as recently found for VXR45, a star with similar rotational propertiesobserved by us with XMM/Newton. If rotational modulation is a generalcharacteristic of supersaturated stars, we will be able to determine thepresence of an asymmetric distribution of coronal structures in such stars andfrom their (or lack of) spectral variations, to infer the characteristics ofsuch structures constraining the properties of the underlying dynamo. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
