Brazilian Journal of Physics, 2013 The concept of stars being tidally ripped apart and consumed by a massive black hole (MBH) lurking in the center of a galaxy first captivated theorists in the late 1970s. The observational evidence for these rare but illuminating phenomena for probing otherwise dormant MBHs first emerged in archival searches of the soft X-ray ROSAT All-Sky Survey in ...

TIDAL DISRUPTION FLARES: THE ACCRETION DISK PHASE [PDF]
The Astrophysical Journal, 2011 The evolution of an accretion disk, formed as a consequence of the disruption of a star by a black hole, is followed by solving numerically the hydrodynamic equations. The present investigation aims to study the dependence of resulting light curves on dynamical and physical properties of such a transient disk during its existence.

Revisit the Rate of Tidal Disruption Events: The Role of the Partial Tidal Disruption Event
The Astrophysical Journal, 2022 Abstract Tidal disruption of stars in dense nuclear star clusters containing supermassive central black holes (SMBH) is modeled by high-accuracy direct N-body simulation. Stars getting too close to the SMBH are tidally disrupted, and a tidal disruption event (TDE) happens.

Neutrinos from tidal disruption events [PDF]
Nature Astronomy, 2021 Tidal disruption events are an excellent probe for supermassive black holes in distant inactive galaxies because they show bright multi-wavelength flares lasting several months to years. AT2019dsg presents the first potential association with neutrino emission from such an explosive event.

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 ...

Underluminous tidal disruptions
, 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 a $t^{-5/3}$ decay.

GSN 069 – A tidal disruption near miss [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 ABSTRACT I suggest that the quasi-periodic ultrasoft X-ray eruptions recently observed from the galaxy GSN 069 may result from accretion from a low-mass white dwarf in a highly eccentric orbit about its central black hole. At $0.21\,\rm M_{\odot }$, this star was probably the core of a captured red giant.
