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

The optical, UV-plateau, and X-ray tidal disruption event luminosity functions reproduced from first principles [PDF]
Monthly Notices of the Royal Astronomical SocietyWe reproduce the luminosity functions of the early-time peak optical, the late-time UV plateau, and the peak X-ray luminosities of tidal disruption events, using an entirely first-principles theoretical approach.

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.

Revisit the Rate of Tidal Disruption Events: The Role of the Partial Tidal Disruption Event [PDF]
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.

An Earth-sized Planet on the Verge of Tidal Disruption [PDF]
Astronomical JournalTOI-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 ⊕.

Resonant tidal disruption in galactic nuclei [PDF]
Monthly 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.

Double Tidal Disruption Events or Repeating Partial Tidal Disruption Events in AT 2020vdq
The Astrophysical JournalAT 2020vdq has been known as a candidate of repeating partial tidal disruption events (pTDEs) due to its two flares with a time interval of ∼1000 days.

A New Population of Mid-infrared-selected Tidal Disruption Events: Implications for Tidal Disruption Event Rates and Host Galaxy Properties [PDF]
The Astrophysical JournalMost tidal disruption events (TDEs) are currently found in time-domain optical and soft X-ray surveys, both of which are prone to significant obscuration. The infrared (IR), however, is a powerful probe of dust-enshrouded environments; hence, we recently

Relativistic tidal disruption events [PDF]
EPJ Web of Conferences, 2012 In March 2011 Swift detected an extremely luminous and long-lived outburst from the nucleus of an otherwise quiescent, low luminosity (LMC-like) galaxy. Named Swift J1644+57, its combination of high-energy luminosity (1048 ergs s−1 at peak), rapid X-ray ...

Stellar dynamics and tidal disruption events in galactic nuclei [PDF]
EPJ Web of Conferences, 2012 The disruption of a star by the tidal field of a massive black hole is the final outcome of a chain of complex dynamical processes in the host galaxy. I introduce the “loss cone problem”, and describe the many theoretical and numerical challenges on the ...
