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.
