Title: The UV Emission in the Decay of a Tidal Disruption Event

Abstract: Stars approaching a supermassive black hole (SMBH) can be tidally disrupted and subsequently accreted. Such kind of tidal disrupt events (TDEs) provides a unique way to find and study inactive SMBHs and may also provide an important mechanism of growing them. Only about twenty such candidates have been reported. Following-up of such events is important to constrain their long-term evolution to help to pin down their nature and strengthen the TDE theory. We have a TDE candidate whose recent follow-up observations indicate a decaying non-stellar UV continuum, which should originate from our event. We request for SOAR monitoring of this UV emission to help to understand the decay properties of such events in UV and the circumnuclear environment.
