# TESS Program G09101 Title: TESS Constraints On The Rises And Bumps Of Tidal Disruption Events PI: Hinkle, Jason - University Of Illinois At Urbana-Champaign Type: SMALL Summary: A tidal disruption event (TDE) occurs when a star is ripped apart by a supermassive black hole (SMBH). Many TDE models are sensitive to the early-time emission, a phase that is currently poorly constrained. We propose to use the high cadence and high precision photometry of TESS to probe the early phases of TDEs, which encode information on the disrupted star and SMBH. Strong constraints on TDE rise times, slopes, and bumps will inform theoretical models on how the first light from TDEs is produced. These parameters may also connect to the SMBH s environment. TESS will also place deep limits on pre-existing AGN activity in TDE host galaxies. We expect TESS to detect at least 1-2 new TDEs in Cycle 9, as well as 15+ additional TDEs with pre-flare TESS observations of their host galaxy.
