Scientific paper

We propose to obtain RGS spectra and EPIC light curves and spectra of the magnetic Be star beta Cep, to provide stringent tests of the magnetically confined wind shock model proposed to explain the X-ray emission observed from this star. Measurement of the density from the O VII triplet (as well as of the Ne and Mg triplets), of the line broadening, and determination of the rotational modulation of the spectral characteristics will allow to discriminate X-ray emission due to this novel mechanism from either coronal emission or emission due to the shocked winds observed in non-magnetic high-mass stars.
