Tidal disruption events (TDEs) are not the primary power source for most observed active galactic nuclei (AGNs) in dwarf galaxies.
The detection of quasi-periodic X-ray eruptions from a known tidal disruption event suggests that these eruptions could be caused by an orbiting body colliding with the accretion disk formed after a star is disrupted by a supermassive black hole.
The observation of two optical flares separated by 10.3 years in the galaxy IRAS F01004-2237 suggests the occurrence of recurring tidal disruption events (TDEs), potentially caused by repeating partial TDEs, double TDEs, or two independent TDEs.
IRAS F01004-2237で約10年離れて2度の光学フレアが観測され、どちらも潮汐破壊現象 (TDE) である可能性が高いことが示唆された。
