Notes. Column 1: name of the TDE. Column 2: time separation between the peaks (the parenthesis for AT 2022exr is the time separation between the second and third flares). Column 3: number of flares. Column 4: partial TDE scenario. Column 5: disruption of a stellar binary scenario. Column 6: disruption of separate stars scenario. Column 7: other potential mechanism (α = TDE followed by SN, β = accretion disc fluctuation or a sudden influx of excess orbiting material from the disrupted star).
