Description
We have discovered an unprecedentedly long ($>$10 YRS) x-RAY tidal disruption event candidate. IT showed several interesting signatures of super-eddington accretion: quasisoft x-RAY spectra, eddington-limited luminosity, and later transition to the thermal state of much softer spectra. Therefore this event provides a unique opportunity for study of super-eddington accretion onto supermassive black holes. The source now apprears to be in the thermal state. We request XMM-newton to have one more observation in AO18 on this target, two years after the last monitoring and when the event is turning to a phase of faster decay. Continued monitoring is critical for the modeling of the event and ation of its nature as the most spectacular tidal disruption event known.
