Description Tidal disruption events (TDEs), where a star is disrupted while passing close to a black hole, enable a view of accretion onto supermassive objects from quiescence to super-Eddington rates, on a timescale of a few years. Here we propose to characterise the spectral and temporal properties two TDEs found in AO15. As part of a comprehensive multiwavelength campaign we will use XMM-Newton and HST to map either side of the expected hot black-body peak; search for evidence of non-thermal components; track the cooling of the event and study the long and short timescale variability of the sources. In doing so we will create exquisite, panchromatic pictures of these extreme events.

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.
