Recent efforts to understand exotic phenomena in galactic nuclei commonly postulate the presence of a massive black hole accreting gas produced by tidal or collisional disruption of stars. For black holes in the mass range 104–107 M\cirċ, individual stars penetrating well inside the Roche radius will undergo compression to a short-lived pancake configuration very similar to that produced by a high velocity symmetric collision of the kind likely to occur in the neighbourhood of black… 
Tidal disruption of stars by black holes of 106–108 solar masses in nearby galaxies
Stars in galactic nuclei can be captured or tidally disrupted by a central black hole. Some debris would be ejected at high speed', the remainder would be swallowed by the hole, causing a bright
Modelling the light-curves of objects tidally disrupted by a black hole
Tidal disruption by massive black holes is a phenomenon, during which a large part of gravitational energy can be released on a very short time-scale. The time-scales and energies involved during
Rates of tidal disruption of stars by massive central black holes
There is strong evidence for some kind of massive dark object in the centres of many galaxy bulges. The detection of flares from tidally disrupted stars could confirm that these objects are black
The Fate of Stars in the Vicinity of Supermassive Black Holes
When a star approaches the neighborhood of a supermassive black hole, the tidal forces acting on the star trigger a vast range of physical effects that could yield unique observational signatures. Of
Tidal disruption of white dwarfs by intermediate mass black holes
Modeling ultra-close encounters between a white dwarf and a spinning, intermediate mass black hole requires a full general relativistic treatment of gravity. This paper summarizes results from such a
Gravitational Waves and X-Ray Signals from Stellar Disruption by a Massive Black Hole
Gravitational waves and X-ray flares are expected from tidal disruption of stars by a massive black hole. Using a relativistic smoothed particle hydrodynamics code, we investigate the fate of
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.
Stellar dynamics and tidal disruption events in galactic nuclei
The disruption of a star by the tidal field of a massive black hole is the final outcome of a chain of complex dynamical processes in the host galaxy. I introduce the "loss cone problem", and
THE TIDAL DISRUPTION OF GIANT STARS AND THEIR CONTRIBUTION TO THE FLARING SUPERMASSIVE BLACK HOLE POPULATION
Sun-like stars are thought to be regularly disrupted by supermassive black holes (SMBHs) within galactic nuclei. Yet, as stars evolve off the main sequence their vulnerability to tidal disruption
Relativistic tidal compressions of a star by a massive black hole
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

A two-dimensional hydrodynamic code has been developed for numerical studies of stellar collisions. The motivation for the study has been the suggestion by Colgate that collisions among stars in a

Quasars are interpreted as massive black holes in galactic nuclei which are fuelled by capturing gas or stars from their surroundings. This paper discusses the supply of gas, the nature of the inflow
