When a star is tidally disrupted by a supermassive black hole the rapid accretion of the stellar debris may drive super-Eddington winds which. After a period of accretion rate decay we expect the winds to shut off drastically reducing the production of broad line emission and changing the evolution of the band-specific light curve across the spectrum. Spectroscopic monitoring of new tidal disruption events (TDEs) in the ultraviolet is the best place to observe this transition due to the persistence of a windless disk continuum. the lack of stellar contamination and the wealth of high-ionization diagnostic lines that probe the relatively small TDE accretion structure. We propose to observe 5 TDEs over 3 epochs with monitoring UV spectroscopy and complementary X-ray and optical [truncated! Please see actual data for full text]
