|Title||X-rays from Classical FU Orionis Stars|
|Author||Dr Stephen Skinner|
|Description||FU Orionis objects (FUors) are a remarkable class of low-mass pre-main-sequence stars that are undergoing disk accretion at very high rates. Classical FUors have all experienced dramatic optical outbursts attributed to a sudden increase in the disk accretion rate. Because of their youth and strong accretion, FUors should be X-ray sources. However, X-ray observations are almost non- existent. We detected the prototype FU Ori in a short 17 ksec XMM-EPIC observation in AO-3, but the data are affected by high background radiation. We propose here to reobserve FU Ori and to obtain first observations of the three other known classical FUors. These observations will define the properties of this newly discovered class of X-ray sources.|

|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.
