Unbound Debris Streams and Remnants Resulting From the Tidal Disruptions of Stars by Supermassive Black Holes
The kinetic energy of a star in orbit about a supermassive black hole is a significant fraction of its rest mass energy when its periapse is comparable to its tidal radius. Upon its destruction, a fraction of this energy is extracted and injected into the stellar debris, half of which becomes unbound from the black hole, with the fastest material moving at ∼ 0.03c. In this paper, we present a f...
متن کاملTidal Capture of Stars by Intermediate-Mass Black Holes
Recent X-ray observations and theoretical modelling have made it plausible that some ultraluminous X-ray sources (ULX) are powered by intermediate-mass black holes (IMBHs). N-body simulations have also shown that runaway merging of stars in dense star clusters is a way to form IMBHs. In the present paper we have performed N -body simulations of young clusters such as MGG-11 of M82 in which IMBH...
متن کاملTidal Interactions and Disruptions of Giant Planets on Highly Eccentric Orbits
We calculate the evolution of planets undergoing a strong tidal encounter using smoothed particle hydrodynamics (SPH), for a range of periastron separations. We find that outside the Roche limit, the evolution of the planet is well-described by the standard model of linear, non-radial, adiabatic oscillations. If the planet passes within the Roche limit at periastron, however, mass can be stripp...
متن کاملSchwarzschild Black Holes from Matrix Theory
We consider Matrix theory compactified on T 3 and show that it correctly describes the properties of Schwarzschild black holes in 7 + 1 dimensions, including the energy–entropy relation, the Hawking temperature and the physical size, up to numerical factors of order unity. The most economical description involves setting the cut-off N in the discretized light-cone quantization to be of order th...
متن کاملSchwarzschild Black Holes from Brane-Antibrane Pairs
We show that D=4 Schwarzschild black holes can arise from a doublet of Euclidean D3-D3 pairs embedded in D=10 Lorentzian spacetime. By starting from a D=10 type IIB supergravity description for the D3 − D3 pairs and wrapping one of them over an external 2-sphere, we derive all vacuum solutions compatible with the symmetry of the problem. Analysing under what condition a Euclidean brane configur...
