Extremely Relativistic Tidal Disruption Events
The Astrophysical Journal Letters, 2023 Extreme tidal disruption events (eTDEs), which occur when a star passes very close to a supermassive black hole, may provide a way to observe a long-sought general relativistic effect: orbits that wind several times around a black hole and then leave ...

A radio-emitting outflow produced by the tidal disruption event AT2020vwl [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 A tidal disruption event (TDE) occurs when a star is destroyed by a supermassive black hole. Broadband radio spectral observations of TDEs trace the emission from any outflows or jets that are ejected from the vicinity of the supermassive black hole ...

Underluminous tidal disruption events [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 We have evidence of X-ray flares in several galaxies consistent with a a star being tidally disrupted by a supermassive black hole (MBH). If the star starts on a nearly parabolic orbit relative to the MBH, one can derive that the fallback rate follows ...

AT2019azh: an unusually long-lived, radio-bright thermal tidal disruption event [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 Tidal disruption events (TDEs) occur when a star is destroyed by a supermassive black hole at the center of a galaxy, temporarily increasing the accretion rate onto the black hole and producing a bright flare across the electromagnetic spectrum.

Relativistic tidal disruption events [PDF]
EPJ Web of Conferences, 2012 In March 2011 Swift detected an extremely luminous and long-lived outburst from the nucleus of an otherwise quiescent, low luminosity (LMC-like) galaxy. Named Swift J1644+57, its combination of high-energy luminosity (1048 ergs s−1 at peak), rapid X-ray ...

Jets from Tidal Disruption Events [PDF]
New Astronomy Reviews, 2020 The discovery of jets from tidal disruption events (TDEs) rejuvenated the old field of relativistic jets powered by accretion onto supermassive black holes. In this Chapter, we first review the extensive multi-wavelength observations of jetted TDEs. Then, we show that these events provide valuable information on many aspects of jet physics from a new ...

Time scales in tidal disruption events [PDF]
EPJ Web of Conferences, 2012 We explore the temporal structure of tidal disruption events pointing out the corresponding transitions in the lightcurves of the thermal accretion disk and of the jet emerging from such events.

Double Tidal Disruption Events or Repeating Partial Tidal Disruption Events in AT 2020vdq
The Astrophysical JournalAT 2020vdq has been known as a candidate of repeating partial tidal disruption events (pTDEs) due to its two flares with a time interval of ∼1000 days.

Abundance Anomalies In Tidal Disruption Events [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 The ~10% of tidal disruption events (TDEs) due to stars more massive than the Sun should show abundance anomalies due to stellar evolution in helium, carbon and nitrogen, but not oxygen.
