Delayed radio flares from a tidal disruption event [PDF]

open access: yesNature Astronomy, 2021
Radio observations of tidal disruption events (TDEs)—when a star is tidally disrupted by a supermassive black hole (SMBH)—provide a unique laboratory for studying outflows in the vicinity of SMBHs and their connection to accretion onto the supermassive ...

Resonant tidal disruption in galactic nuclei [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
It has recently been shown that the rate of angular momentum relaxation in nearly-Keplerian star clusters is greatly increased by a process termed resonant relaxation (Rauch & Tremaine 1996), who also argued that tidal disruption of stars in galactic nuclei containing massive black holes could be noticeably enhanced by this process.

Radio Observations of an Ordinary Outflow from the Tidal Disruption Event AT2019dsg [PDF]

open access: yesAstrophysical Journal, 2021
We present detailed radio observations of the tidal disruption event (TDE) AT2019dsg, obtained with the Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA), and spanning 55–560 days post disruption.

DOUBLE TIDAL DISRUPTIONS IN GALACTIC NUCLEI [PDF]

open access: yesThe Astrophysical Journal, 2015
A star on a nearly radial trajectory approaching a massive black hole (MBH) gets tidally disrupted if it comes sufficiently close to the MBH. Here we explore what happens to binary stars whose centers of mass approach the MBH on nearly radial orbits. The interaction with the MBH often leads to both stars being disrupted in sequence.

A bright year for tidal disruptions [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2016
When a star is tidally disrupted by a supermassive black hole (BH), roughly half of its mass falls back to the BH at super-Eddington rates. Being tenuously gravitationally bound and unable to cool radiatively, only a small fraction f_in << 1 of the returning debris will likely be incorporated into the disk and accrete, with the vast majority ...

Tidal disruption event demographics [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2016
We survey the properties of stars destroyed in TDEs as a function of BH mass, stellar mass and evolutionary state, star formation history and redshift.

Infrared Echoes of Optical Tidal Disruption Events: ∼1% Dust-covering Factor or Less at Subparsec Scale [PDF]

open access: yesAstrophysical Journal, 2021
The past decade has experienced an explosive increase of optically discovered tidal disruption events (TDEs) with the advent of modern time-domain surveys.

Tidal disruption events and quasi‐periodic eruptions

open access: yesAstronomische Nachrichten, 2023
Tidal disruption events (TDEs) occur when a star passes close to a massive black hole so that the tidal forces of the black hole exceed the binding energy of a star and cause it to be ripped apart. Part of the matter will fall onto the black hole, causing a strong increase in luminosity.

Rapid Accretion State Transitions following the Tidal Disruption Event AT2018fyk [PDF]

open access: yesAstrophysical Journal, 2021
Following a tidal disruption event (TDE), the accretion rate can evolve from quiescent to near-Eddington levels and back over timescales of months to years.

AT2021lwx: Another Neutrino-coincident Tidal Disruption Event with a Strong Dust Echo? [PDF]

open access: yesAstrophysical Journal
We discuss the possible association of an astrophysical neutrino (IC220405B) with the recently reported, extremely energetic tidal disruption event (TDE) candidate AT2021lwx (ZTF20abrbeie, aka “Scary Barbie”) at redshift z = 0.995.
