Supermassive black holes have powerful gravitational fields with strong gradients that can destroy stars that get too close, producing a bright flare in ultraviolet and X-ray spectral regions from stellar debris that forms an accretion disk around the black hole. The aftermath of this process may have been seen several times over the past two decades in the form of sparsely sampled, slowly fading emission from distant galaxies, but the onset of the stellar disruption event has not hitherto been… 
A radio jet from the optical and x-ray bright stellar tidal disruption flare ASASSN-14li
TLDR
Radio follow-up observations of known thermal stellar tidal disruption flares (TDFs) are monitored and a detection of variable radio emission from a thermal TDF, which is interpreted as originating from a newly launched jet, suggests that all TDFs could be accompanied by a jet.
Birth of a relativistic outflow in the unusual γ-ray transient Swift J164449.3+573451
TLDR
It is concluded that the tidal disruption of a star naturally explains the observed high-energy properties and radio luminosity and the inferred rate of such events, and the weaker beaming in the radio-frequency spectrum relative to γ-rays or X-rays suggests that radio searches may uncover similar events out to redshifts of z ≈ 6.
JETS FROM STELLAR TIDAL DISRUPTIONS BY SUPERMASSIVE BLACK HOLES
The tidal disruption of a star by a supermassive black hole provides us with unique information for otherwise dormant galactic nuclei. It has long been predicted that the disruption will be
An ultraviolet–optical flare from the tidal disruption of a helium-rich stellar core
TLDR
A luminous ultraviolet–optical flare from the nuclear region of an inactive galaxy at a redshift of 0.1696 is reported and it is determined that the disrupted star was a helium-rich stellar core, modulo a factor dependent on the mass and radius of the star disrupted.
Prompt emission from tidal disruptions of white dwarfs by intermediate mass black holes
We present a qualitative picture of prompt emission from tidal disruptions of white dwarfs (WD) by intermediate mass black holes (IMBH). The smaller size of an IMBH compared to a supermassive black
JETS FROM TIDAL DISRUPTIONS OF STARS BY BLACK HOLES
Tidal disruption of main-sequence stars by black holes has generally been thought to lead to a signal dominated by UV emission. If, however, the black hole spins rapidly and the poloidal magnetic
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.
Tidal disruption of stars by supermassive black holes: The X-ray view
The tidal disruption of stars by supermassive black holes produces luminous soft X-ray accretion flares in otherwise inactive galaxies. First events have been discovered in X-rays with the ROSAT
Ultra-Close Encounters of Stars With Massive Black Holes: Tidal Disruption Events With Prompt Hyperaccretion
A bright flare from a galactic nucleus followed at late times by a $t^{-5/3}$ decay in luminosity is often considered the signature of the complete tidal disruption of a star by a massive black hole.
Search for high energy gamma-ray emission from tidal disruption events with the Fermi Large Area Telescope
Massive black holes at galaxy center may tear apart a star when the star passes occasionally within the disruption radius, which is the so-called tidal disruption event(TDE). Most TDEs radiate with

A Possible Relativistic Jetted Outburst from a Massive Black Hole Fed by a Tidally Disrupted Star
TLDR
Observations suggest a sudden accretion event onto a central MBH of mass about 106 to 107 solar masses, which leads to a natural analogy of Sw 1644+57 to a temporary smaller-scale blazar.
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, releasing a flare of energy. In anticipation of upcoming transient
Multiband light curves of tidal disruption events
Unambiguous detection of the tidal disruption of a star would allow an assessment of the presence and masses of supermassive black holes in quiescent galaxies. It would also provide invaluable

Theory suggests that a star making a close passage by a supermassive black hole at the center of a galaxy can under most circumstances be expected to emit a giant flare of radiation as it is

LUMINOUS THERMAL FLARES FROM QUIESCENT SUPERMASSIVE BLACK HOLES
A dormant supermassive black hole lurking in the center of a galaxy will be revealed when a star passes close enough to be torn apart by tidal forces, and a flare of electromagnetic radiation is
Candidate tidal disruption events from the XMM-Newton slew survey
Context. In recent years, giant amplitude X-ray flares have been observed from a handful of non-active galaxies. The most plausible scenario of these unusual phenomena is tidal disruption of a star

Aims. We investigate the stellar pancake mechanism during which a solar-type star is tidally flattened within its orbital plane as it passes close to a 10 6 Mblack hole. Methods. We simulated the
