A simple and accurate prescription for the tidal disruption radius of a star and the peak accretion rate in tidal disruption events [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2022 A star destroyed by a supermassive black hole (SMBH) in a tidal disruption event (TDE) enables the study of SMBHs. We propose that the distance within which a star is completely destroyed by a SMBH, defined rt, c, is accurately estimated by equating ...

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.

Tidal Disruption Flares as the Source of Ultra-high Energy Cosmic Rays [PDF]
, 2012 The optical spectral energy distributions of two tidal disruption flares identified by van Velzen et al. (2011) in archival SDSS data, are found to be well-fit by a thin-accretion-disk model.

A detailed spectroscopic study of Tidal Disruption Events [PDF]
, 2021 Spectroscopically, tidal disruption events (TDEs) are characterized by broad ( ∼ 10 4 kms − 1 ) emission lines and show a large diversity as well as di ff erent line profiles.

A Model for the Possible Connection Between a Tidal Disruption Event and Quasi-periodic Eruption in GSN 069 [PDF]
Astrophysical Journal, 2022 Quasi-periodic eruptions (QPEs) are found in the center of five galaxies, where a tidal disruption event (TDE)-like event has been reported in GSN 069, which occurred a couple of years before the QPEs.

GRB060218 as a Tidal Disruption of a White Dwarf by an Intermediate Mass Black Hole [PDF]
, 2013 A highly unusual pair of a gamma-ray burst (GRB) GRB060218 and an associated supernova SN2006aj has puzzled theorists for years. A supernova shock breakout and a jet from a newborn stellar mass compact object were put forward to explain its ...

AT 2020wey and the class of faint and fast tidal disruption events [PDF]
Astronomy & Astrophysics, 2022 We present an analysis of the optical and UV properties of AT 2020wey, a faint and fast tidal disruption event (TDE) at 124.3 Mpc. The light curve of the object peaked at an absolute magnitude of $M_{g} = -17.45$ mag and a maximum bolometric luminosity ...

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.

Tidal flares and rates from an archival cluster survey
EPJ Web of Conferences, 2012 Tidal disruption flares (TDFs) are potent indicators of the co-evolution of galaxies and the massive black holes (MBHs) which they host in their nuclei, both in terms of the individual black holes revealed by tidal flares and in terms of the overall ...

On the Impact of Relativistic Gravity on the Rate of Tidal Disruption Events [PDF]
Astrophysical Journal, 2022 The tidal disruption of stars by supermassive black holes (SMBHs) probes relativistic gravity. In the coming decade, the number of observed tidal disruption events (TDEs) will grow by several orders of magnitude, allowing statistical inferences of the ...
