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 ...

Quasi-periodic X-ray eruptions years after a nearby tidal disruption event. [PDF]

Nature
Quasi-periodic eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks1–5. The mechanism behind these rare systems is uncertain, but most theories involve accretion disks around ...

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.

Revisit the rate of tidal disruption events: the role of the partial tidal disruption event

The Astrophysical Journal, 2022
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)

Fundamental scaling relationships revealed in the optical light curves of tidal disruption events [PDF]

Monthly Notices of the Royal Astronomical Society, 2023
We present fundamental scaling relationships between properties of the optical/UV light curves of tidal disruption events (TDEs) and the mass of the black hole that disrupted the star. We have uncovered these relations from the late-time emission of TDEs.

An Earth-sized Planet on the Verge of Tidal Disruption [PDF]

Astronomical Journal
TOI-6255 b (GJ 4256) is an Earth-sized planet (1.079 ± 0.065 R _⊕ ) with an orbital period of only 5.7 hr. With the newly commissioned Keck Planet Finder and CARMENES spectrographs, we determine the planet’s mass to be 1.44 ± 0.14 M _⊕ .

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

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.

Tidal Disruption Encores [PDF]

The Astrophysical Journal Letters
Nuclear star clusters (NSCs), made up of a dense concentration of stars and the compact objects they leave behind, are ubiquitous in the central regions of galaxies surrounding the central supermassive black hole (SMBH).

Resonant tidal disruption in galactic nuclei [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
It has recently been shown by Rauch & Tremaine that the rate of angular momentum relaxation in nearly Keplerian star clusters is greatly increased by a process termed ‘resonant relaxation’; it was also argued, via a series of scaling arguments, that ...

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.
