AT2023vto: An Exceptionally Luminous Helium Tidal Disruption Event from a Massive Star
We present optical/UV observations and the spectroscopic classification of the transient AT2023vto as a tidal disruption event (TDE) at z = 0.4846. The spectrum is dominated by a broad blueshifted He ii λ 4686 emission line, classifying it as a member of the TDE-He class. The light curve exhibits a...
