Title: Reverberation mapping of stellar tidal disruption flares

Abstract: The Gaia satellite will perform an unbiased, magnitude-limited survey of the transient sky. The key advantages of Gaia over other transient surveys are its high angular resolution, accurate photometry and simultaneous low-resolution spectroscopy. We are currently using Gaia’s unique capabilities to efficiently discriminate the rare stellar tidal disruption flares (TDFs) from much more frequent supernovae. We will use 4-meter class telescopes to obtain spectroscopic follow-up observations of every nuclear transient found by Gaia. Here we request Gemini TOO observations of spectroscopically confirmed TDF candidates that are caught before reaching their peak luminosity. The proposed observations will enable us to measure where the emission lines of TDFs are produced.
