Abstract FU Orionis objects (FUors) are a remarkable class of low-mass pre-main-sequencestars that are undergoing disk accretion at very high rates. The classical FUorshave all experienced dramatic optical outbursts attributed to a sudden increasein the disk accretion rate. Because of their youth and strong accretionsignatures, FUors should be X-ray sources. Surprisingly, X-ray data for FUorsare almost nonexistent and little is known about their X-ray attributes. Wepropose to observe three FUors with XMM-EPIC in order to determine the basicX-ray properties of the class. Our targets include the prototype FU Orionis andthe classical FUor V1057 Cyg, which is known to have been a T Tauri star priorto its optical outburst in 1970.

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.
