Description We have discovered a decade-long X-ray tidal disruption candidate, which recent observations suggest to be still in the super-Eddington accretion phase but with sporadic dramatic spectral softening. We request three XMM-Newton monitorings in AO16 on this target, which is unique for study of the super-Eddington accretion onto supermassive black holes. The goals are to confirm its still being in the super-Eddington accretion phase and to measure the spectral softening occurrence rate, allowing us to determine whether the spectral softening is due to transient high-speed warm absorbers or state transition. We also request an HST orbit to help confirm the nuclear origin of the event and study its environment.

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.
