We propose a semi-analytical model for the self-intersection of the fallback stream in tidal disruption events (TDEs). When the blackhole mass exceeds a critical value M_cr, a large fraction of the shocked gas becomes unbound, in the form of a collision-induced outflow (CIO). This is because the large apsidal precession causes the stream to self-intersect near the local escape speed at radius much below the apocenter. The rest of the fallback gas is left in more tightly bound orbits and quickly… Expand
Simulating disc formation in tidal disruption events
A star coming too close to a supermassive black hole gets disrupted by the tidal force of the compact object in a tidal disruption event, or TDE. Following this encounter, the debris evolves into anExpand
Two regimes of tidal-stream circularization by supermassive black holes
Stars that approach a supermassive black hole (SMBH) too closely can be disrupted by the tidal gravitational field of the SMBH. The resulting debris forms a tidal stream orbiting the SMBH which canExpand
On the Origin of Late-time X-Ray Flares in UV/optically Selected Tidal Disruption Events
We propose a model to explain the time delay between the peak of the optical and X-ray luminosity, Δt O−X hereafter, in UV/optically selected tidal disruption events (TDEs). The following pictureExpand
The late flare in tidal disruption events due to the interaction of disk wind with dusty torus
Abstract A late (t ∼ 1,500 days) multi-wavelength (UV, optical, IR, and X-ray) flare was found in PS1-10adi, a tidal disruption event (TDE) candidate that took place in an active galactic nucleusExpand

We use the general relativistic radiation magnetohydrodynamics code KORAL to simulate the accretion disc formation resulting from the tidal disruption of a solar mass star around a supermassiveExpand
Radiative Emission Mechanisms of Tidal Disruption Events.
We describe how the various outcomes of stellar tidal disruption give rise to observable radiation. We separately consider the cases where gas circularizes rapidly into an accretion disc, as well asExpand
Wind-reprocessed Transients
We consider the situation where the luminosity from a transient event is reprocessed by an optically thick wind. Potential applications are the tidal disruption of stars by black holes,Expand
Decelerated non-relativistic expansion in a tidal disruption event with a potential neutrino association
A tidal disruption event (TDE) involves the tidal shredding of a star in the vicinity of a dormant supermassive black hole. The nearby (≈230 mega-parsec) radio-quiet (radio luminosity of 4 × 10 ergExpand
Dynamical structure of highly eccentric discs with applications to tidal disruption events
Whether tidal disruption events circularise or accrete directly as highly eccentric discs is the subject of current research and appears to depend sensitively on the disc thermodynamics. One aspectExpand
X-ray flares from the stellar tidal disruption by a candidate supermassive black hole binary
TLDR
The discovery of delayed X-ray brightening around 140 days after the optical outburst in the TDE OGLE16aaa, followed by several flux dips during the decay phase implies that the reprocessing is important in theTDE early evolution, andX-ray observations are promising in revealing supermassive black hole binaries.
