Notes. (1) Redshift. (2) Time interval between the two flares. (3) SMBH mass in unit of M⊙. Data from the literature, except for AT 2024pvu. (4),(5) Total energy E (or peak V-band luminosity LV) of the first and second flares, in unit of erg (erg s−1). The total energy for AT 2019azh.I is poorly constrained owing to the lack of data, so we only provide LV. (6) Ratio of the energy (or LV) of the second flare to that of the first flare. (7)(8) Semi-major axis a (in unit of AU) and eccentricity e (given in β (1 − e)) in the rpTDE model. (9) Peak time of the next flare predicted by the rpTDE model. (10) References: 1. Lin et al.
