X-ray emission from young stars is a crucial agent in the formation of planetarysystems, driving the chemistry and eventual dispersal of protoplanetary disks.K2.s 80-day monitoring of young stars in the Taurus star-forming region showsdramatic variability that points to changes in levels of accretion,circumstellar absorption and magnetic activity on timescales of days to weeks.Similar variability is expected in X-rays, causing important changes in thehigh-energy irradiation of planet-forming disks, but is largely unexplored inX-rays. Therefore, we propose the first large-scale X-ray monitoring campaign ofwell-characterized T Tauri stars with this cadence.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
