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
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
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.

Implications from Late-time X-Ray Detections of Optically Selected Tidal Disruption Events: State Changes, Unification, and Detection Rates
Using Chandra X-ray observations we detect three out of four optically-selected tidal disruption events (TDEs) 4-9 years after their discovery. The spectrum of PTF09axc is consistent with a power lawExpand
The UV/optical peak and X-ray brightening in TDE candidate AT2019azh: A case of stream-stream collision and delayed accretion
We present and analyze the optical/UV and X-ray observations of a nearby tidal disruption event (TDE) candidate AT2019azh, spanning from 30 d before to ~ 250 d after its early optical peak. TheExpand

A Dark Year for Tidal Disruption Events
The disruption of a main-sequence star by a supermassive black hole results in the initial production of an extended debris stream that winds repeatedly around the black hole, producing a complexExpand
Magnetohydrodynamical simulations of a deep tidal disruption in general relativity
We perform hydro- and magnetohydrodynamical general-relativistic simulations of a tidal disruption of a 0.1 M_⊙ red dwarf approaching a 10^5 M_⊙ non-rotating massive black hole on a close (impactExpand
Disc formation from tidal disruptions of stars on eccentric orbits by Schwarzschild black holes
The potential of tidal disruption of stars to probe otherwise quiescent supermassive black holes cannot be exploited, if their dynamics is not fully understood. So far, the observational appearanceExpand
PS1-10jh: The disruption of a main-sequence star of near-solar composition
When a star comes within a critical distance to a supermassive black hole (SMBH), immense tidal forces disrupt the star, resulting in a stream of debris that falls back onto the SMBH and powers aExpand
Soft X-ray Temperature Tidal Disruption Events from Stars on Deep Plunging Orbits
One of the puzzles associated with tidal disruption event candidates (TDEs) is that there is a dichotomy between the color temperatures of ${\rm few}\times 10^4$~K for TDEs discovered with opticalExpand
Long-term stream evolution in tidal disruption events
A large number of tidal disruption event (TDE) candidates have been observed recently, often differing in their observational features. Two classes appear to stand out: X-ray and optical TDEs, theExpand
Optical flares from the tidal disruption of stars by massive black holes
A star that wanders too close to a massive black hole (BH) is shredded by the BH’s tidal gravity. Stellar gas falls back to the BH at a rate initially exceeding the Eddington rate, releasing a flareExpand

Flares from tidal disruption events are unique tracers of quiescent black holes at the centre of galaxies. The appearance of these flares is very sensitive to whether the star is totally or partiallyExpand
On the structure of tidally-disrupted stellar debris streams
A tidal disruption event (TDE) -- when a star is destroyed by the immense gravitational field of a supermassive black hole -- transforms a star into a stream of tidally-shredded debris. TheExpand
