An analytic model with critical behavior in black hole formation
نویسندگان
چکیده
A simple analytic model is presented which exhibits a critical behavior in black hole formation, namely, collapse of a thin shell coupled with outgoing null fluid. It is seen that the critical behavior is caused by the gravitational nonlinearity near the event horizon. We calculate the value of the critical exponent analytically and find that it is very dependent on the coupling constants of the system. ∗JSPS fellow, e-mail: [email protected] †e-mail: [email protected]

متن کاملThe phase transition of corrected black hole with f(R) gravity
In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...
متن کاملQuasinormal Modes and Choptuik Scaling in the Near Extremal Reissner-Nordström Black Hole
We study quasinormal modes of massless scalar and fermion fields in the near extremal Reissner-Nordström black hole, and relate them to Choptuik scaling form following a recently proposed analytic approach. For both massless cases, quasinormal modes are shown to be proportional to the black hole horizon and the Hawking temperature, and the critical exponents are the same, although for the fermi...
متن کاملCritical Behavior of Black Hole Formation in a Scalar Wave Collapse
Gravitational collapse is one of interesting phenomena in general relativity. In recent years, a large number of studies have been made on the dynamical behavior of a massless scalar field, in the context of spherically symmetric gravitational collapse. It has been shown that for a weak-field implosion scalar waves bounce and disperse to infinity, while a strong-field implosion leads to black h...
متن کاملGravitational collapse in 2+1 dimensional AdS spacetime
We present results of numerical simulations of the formation of black holes from the gravitational collapse of a massless, minimally-coupled scalar field in 2+1 dimensional, axially-symmetric, anti de-Sitter (AdS) spacetime. The geometry exterior to the event horizon approaches the BTZ solution, showing no evidence of scalar ‘hair’. To study the interior structure we implement a variant of blac...
