We propose a novel and decisive experiment that relies on the unrivaled joint capabilities of XMM and HST. The closest O-type star comma zeta Oph comma shall be observed continuously over its rotational period to reveal the physics of stellar wind heating. We will discriminate between alternative models for X-ray production in O starsdoublePoint the hot plasma is generated either in stochastic wind shocks or in corotating interaction regions. The new superb X-ray image will probe the physical conditions in the circumstellar matter of an O star. No similar observations were performed before on a massive star. Observing zeta Oph for 80ks with XMM and 15 HST orbits will allow to study correlated X-ray and UV variability and achieve a breakthrough in our understanding of O stars.
