XMM-Newton follow-up observation of the nearest tidal disruption event

The galaxy NGC 3599 is the closest and most recent candidate for the tidaldisruption of a star by a supermassive black hole. It was discovered to be verysoft in the XMMNewton Slew Survey and followup observations have shown thespectrum hardening while the light curve decays with a t ^{5/3} law. Wepropose to observe NGC 3599 with the XMMNewton EPIC cameras for 40 ks, takingadvantage of their excellent throughput and good spectral resolution, to furtherquantify the spectral evolution of the source and achieve a high significancepoint on the light curve. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
