Description Dramatic optical/IR outbursts from PMS stars, which signal the onset of rapid
mass-infall onto such stars through their accretion disks, cannot be predicted.
However, our X-ray monitoring of the outbursts of V1647 Ori demonstrates that a
high accretion rate can also produce an X-ray outburst, and, indeed, that X-ray
monitoring of PMS accretion outbursts represents a new observational window on
the magnetic interaction between the stellar magnetosphere and the accretion
disk. We propose a 40 ks-exposure XMM-Newton ToO of any optical/IR outburst from
PMS star to perform X-ray spectroscopy with EPIC and to investigate X-ray
variability on a timescale of hours.

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.
