| 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 Chandra and XMM monitoring of the outburst 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 80 ks-exposure XMM ToO of any X-ray outburst, confirmed with Chandra or Swift (short) ToO exposure, to perform X-ray spectroscopy with EPIC and to investigate X-ray variability on a timescale of a day. |

| 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. |
