Tidal effects in 4D Einstein–Gauss–Bonnet black hole spacetime

چکیده
We have investigated tidal forces and geodesic deviation motion in the 4D-Einstein-Gauss-Bonnet spacetime. Our results show that force depend sharply on sign of Gauss-Bonnet coupling constant. Comparing with Schwarzschild spacetime, strength becomes stronger for negative constant, but is weaker positive one. Moreover, behaves like those spacetime as constant negative, Reissner-Nordstr\"{o}m black hole positive. also present change vector under two kinds initial conditions.

Black Hole Evaporation in Noncommutative Spacetime
A toy model based upon the q-deformation description for studying the radiation spectrum of black hole is proposed. The starting point is to try to consider the spacetime noncommutativity and to realize it by using a qdeformation algebraic technique. We calculated the radiation spectrum of Schwarzschild black hole in this framework. The new distribution deviates from the standard thermal spectr...
متن کاملTidal interaction in binary-black-hole inspiral.
Tidal torque may lead to important effects in the strong field interaction at the end point of the inspiral of two rapidly rotating black holes. We point out here that in such a case the exchange of spin and orbital angular momentum may significantly affect the energy and waveform of late stage gravitational waves, and may play an important role in the shedding of excess angular momentum. We ar...

We consider the duality of the quasilocal black hole thermodynamics, explicitly the quasilocal black hole thermodynamic first law, in BTZ black hole solution as a special one of the three-dimensional low energy effective string theory.

متن کاملBlack hole evaporation rates without spacetime.
Verlinde recently suggested that gravity, inertia, and even spacetime may be emergent properties of an underlying thermodynamic theory. This vision was motivated in part by Jacobson's 1995 surprise result that the Einstein equations of gravity follow from the thermodynamic properties of event horizons. Taking a first tentative step in such a program, we derive the evaporation rate (or radiation...
متن کاملSpacetime structure of an evaporating black hole in quantum gravity
The impact of the leading quantum gravity effects on the dynamics of the Hawking evaporation process of a black hole is investigated. Its spacetime structure is described by a renormalization group improved Vaidya metric. Its event horizon, apparent horizon, and timelike limit surface are obtained taking the scale dependence of Newton’s constant into account. The emergence of a quantum ergosphe...
