The Astrophysical Journal LettersNuclear 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).

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.

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.

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 DISRUPTIONS IN GALACTIC NUCLEI [PDF]
The 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]
Monthly 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]
Monthly 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.

Tidal disruption events and quasi‐periodic eruptions
Astronomische 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.

Shock breakouts from tidal disruption events [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 Tidal disruption events of stars by supermassive black holes have so far been discovered months to years after the fact. In this paper we explore the short, faint and hard burst of radiation is emitted at maximum compression, as a result of shock breakout. The detection of this burst can be used to capture tidal disruption events in real time.
