Descripción
Sumario:[Context] Tidal disruption events (TDEs) are usually discovered at X-ray or optical wavelengths through their transient nature. A characteristic spectral feature of X-ray detected TDEs is a ‘supersoft’ X-ray emission, not observed in any other extragalactic source, with the exception of a few rapidly variable hyperluminous X-ray sources (HLXs) or supersoft active galactic nuclei (AGN) that are distinguishable by their optical emission.
