Description 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.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
