Disruption of a Red Giant Star by a Supermassive Black Hole and the Case of PS1-10jh

, 2014
The development of a new generation of theoretical models for tidal disruptions is timely, as increasingly diverse events are being captured in surveys of the transient sky. Recently, Gezari et al.

A New Way to Detect Massive Black Holes in Galaxies: The Stellar Remnants of Tidal Disruption [PDF]

, 2001
We point out that the tidal disruption of a giant may leave a luminous (10^35-10^39 ergs/s), hot (10-100 eV) stellar core. The ``supersoft'' source detected by Chandra at the center of M31 may be such a core; whether or not it is, the observations have ...

Reverberation Evidence for Stream Collision and Delayed Disk Formation in Tidal Disruption Events

The Astrophysical Journal
When a star passes through the tidal disruption radius of a massive black hole (BH), it can be torn apart by the tidal force of the BH, known as the tidal disruption event (TDE).

Constraining the Rate of Relativistic Jets from Tidal Disruptions Using Radio Surveys

, 2011
Tidal disruption of stars by massive black holes produce transient accretion flows that flare at optical, UV, and X-ray wavelengths. At late times, these accretion flows may launch relativistic jets that can be detected through the interaction of the jet

An outflow powers the optical rise of the nearby, fast-evolving tidal disruption event AT2019qiz [PDF]

Monthly notices of the Royal Astronomical Society, 2020
At 66 Mpc, AT2019qiz is the closest optical tidal disruption event (TDE) to date, with a luminosity intermediate between the bulk of the population and the faint-and-fast event iPTF16fnl.

Fallback Rates in Partial Tidal Disruptions of White Dwarfs by Intermediate-mass Black Holes

The Astrophysical Journal
The fallback rate of debris after the partial tidal disruption of a star by an intermediate-mass black hole (IMBH) might provide important signatures of such black holes rather than supermassive ones.

Time scales in tidal disruption events

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.

Enhanced tidal disruption rates from massive black hole binaries

, 2009
"Hard" massive black hole (MBH) binaries embedded in steep stellar cusps can shrink via three-body slingshot interactions. We show that this process will inevitably be accompanied by a burst of stellar tidal disruptions, at a rate that can be several ...

SWIFT J164449.3+573451: a plunging event with the Poynting-flux dominated outflow

, 2012
Swift J164449+573451 is a peculiar outburst which is most likely powered by the tidal disruption of a star by a massive black hole. Within the tidal disruption scenario, we show that the periastron distance is considerably smaller than the disruption ...

The Double Tidal Disruption Event AT 2022dbl Implies that at Least Some “Standard” Optical Tidal Disruption Events Are Partial Disruptions

The Astrophysical Journal Letters
Flares produced following the tidal disruption of stars by supermassive black holes can reveal the properties of the otherwise dormant majority of black holes and the physics of accretion.
