In order to address the question of the origin of X-ray emission in Classical T Tauri stars we propose an XMM-Newton observation of XZ Tau. We propose to monitor the source over 6 days to follow the variation of hydrogen column density in front of the star, over two rotational periods of the star. This will allow a rotational modulation of the hydrogen column density to be detected, if present, and therefore unambiguously identify the existence on XZ Tau of a co-rotating accretion stream shadowing an X-ray bright hot spot. This will be strong evidence for the X-ray emission mechanism being mainly accretion driven.
