| Abstract | In a program, running since AO-7, we have used XMM-Newton, Swift, optical andradio observations to monitor the evolution of four tidal disruption eventsdiscovered by a near-real time comparison of XMM slew data with the ROSATall-sky survey. This work has broadly confirmed the original idea that stellardebris returns to the black hole with an index of -5/3 and emits in the softX-ray band with luminosity following the returning mass. It has shown that thepeak X-ray emission is reprocessed and not simply the high-energy tail ofthermal emission. We now wish to investigate questions raised by these detailedobservations: why do few TDE generate a hard X-ray component? Why is theemission so volatile in the early phase? Why do X-ray selected events not have |

| 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. |
