The Location and Temperature of Event Horizon for General Black Hole via the Method of Damour-Ruffini-Zhao
نویسنده
چکیده
In this paper, we investigate the general case of black hole at horizon by the method of Damour-Ruffini-Zhao. The proof of identification of the location of horizons determined both by Damour-Ruffini-Zhao’s (D-R-Z) method and by equation of null super-surface is given. The formula of temperature on the horizon for general black holes is obtained and is successfully checked by a variety of models of black holes. PACS:

Hawking radiation of Kerr-Newman-de Sitter black hole
We extend the classical Damour-Ruffini method and discuss Hawking radiation in KerrNewman-de Sitter(KNdS) black hole. Under the condition that the total energy, angular momentum and charge of spacetime are conserved, taking the reaction of the radiation of the particle to the spacetime and the relation between the black hole event horizon and the cosmological horizon into consideration, we deri...
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 کامل0 the Relation Between Technique of Conformal Flat and Damour - Ruffini - Zhao ’ s Method
The relation between the technique of conformal flat and Damour-Ruffini-Zhao's method is investigated in this paper. It is pointed out that the two methods give the same results when the metric has the form g αβ=0 , with α = 0, 1 and β = 2, 3. It is indicated that the two methods are not equivalent for general case.
متن کاملHawking radiation of Dirac particles via tunnelling from rotating black holes in de Sitter spaces
Hawking radiation from black hole horizon can be viewed as a quantum tunnelling process, and fermions via tunnelling can successfully recover Hawking temperature. In this paper, considering the tunnelling particles with spin 1/2 (namely, Dirac particles), we further improve Kerner and Man’s fermion tunnelling method to study Hawking radiation via tunnelling from rotating black holes in de Sitte...
متن کاملThin shell wormhole due to dyadosphere of a charged black hole
To explain Gamma Ray Bursts, Ruffini argued that the event horizon of a charged black hole is surrounded by a special region called, the Dyadosphere where electric field exceeds the critical value for e+ e− pair production. In the present work, we construct a thin shell wormhole by performing a thought surgery between two dadospheres. Several physical properties of this thin shell wormhole have...
