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 ...

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.

Abundance Anomalies In Tidal Disruption Events [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 The ~10% of tidal disruption events (TDEs) due to stars more massive than the Sun should show abundance anomalies due to stellar evolution in helium, carbon and nitrogen, but not oxygen.

Tidal Disruption Flares: The Accretion Disk Phase [PDF]
The Astrophysical Journal, 2011 The evolution of an accretion disk, formed as a consequence of the disruption of a star by a black hole, is followed by solving numerically the hydrodynamic equations.

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.
