Abstract	FU Ori objects (FUORs) are late-type pre-main sequence stars in a phase ofstrong accretion. The phenomenon is probably repetitive but with low frequency,so that only 14 objects are classified as confirmed FUORs, with well-monitoredoptical/infrared lightcurves available. About 10 are classified as FUORscandidate. Their X-ray properties (luminosity and temperature) are almostcompletely unconstrained. Given the strong interplay between accretion and X-rayemission throughout the pre-main sequence phase, probed by observations of TTauri stars, this represents an important observational gap. The recentdiscovery of a new FU Ori outburst, V900 Mon, yields a unique opportunity tomonitor in X-rays such an event from early on throughout its decade-long decay. We propose here for the initial 80 ksec pointing.

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.
