| Abstract | We have discovered an unprecedentedly long (>14 yrs) X-ray tidal disruptionevent (TDE) candidate, with several interesting signatures of super-Eddingtonaccretion\: quasi-soft X-ray spectra, Eddington-limited luminosity, and latertransition to the thermal state with much softer spectra. One importantprediction of our identification of the source as a super-Eddington accretingTDE is the significant decrease of the source luminosity and the softening ofthe X-ray spectra in the new few years. Therefore, we request one moreXMM-Newton observation of this event in AO20, two years after the lastmonitoring when it is in a phase of faster decay. Continuing monitoring iscritical for the modeling of the event and confirmation of its nature as the most spectacular TDE known. |

| 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. |
