Long-term Evolution of A New Tidal Disruption Event Candidate

Thanks to its high soft Xray sensitivity, XMMNewton has been used successfullyto constrain the longterm evolution and thus the nature of many candidate tidaldisruption events. Such events occur when stars approach a supermassive blackhole (SMBH) and are tidally disrupted and subsequently accreted, providing aunique way to find and study inactive SMBHs. Only about a dozen of suchcandidates have been reported. Our recently discovered candidate has soft Xrayspectra of unprecedented quality near the flare peak and provides many newdetails such as spectral evolution and fast variability of such events near theflare peak. We propose an XMMNewton followup observation of this source tomeasure its decay curve and spectral evolution to confirm its nature. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
