Thin Shell Wormhole Due to Dyadosphere of a Charged Black Hole

Abstract

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 been analyzed.

Charged gravastars admitting conformal motion

“…Using the Lanczos equations [47,48,49,50,51], one can find the surface stress energy Σ and the surface tangential pressures p θ = p φ ≡ p t :…”

Thin-shell wormholes from charged black holes in generalized dilaton-axion gravity

“…where τ is the proper time on the junction surface. Using the Lanczos equations [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20], one can obtain the surface stress energy tensor S i j = diag(−σ, p θ , p φ ), where σ is the surface energy density and p θ and p φ are the surface pressures. The Lanczos equations now yield [7]…”

“…The resulting structure is a wormhole spacetime in which the throat is a three-dimensional thin shell. In recent years, Visser's approach was adopted by various authors for constructing thin-shell wormholes by similar methods, generally requiring spherical symmetry [2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]. The approach is of special interest because it minimizes the amount of exotic matter required.…”

Stability of thin-shell wormholes from noncommutative BTZ black hole

“…A great amount of works have been found in studying the Chaplygin thin-shell wormholes in [34][35][36][37][38][39][40][41]. The study of thin-shell wormholes have been extended include charge and cosmological constant, as well as other features (see, for example, references [42][43][44][45][46][47][48][49][50][51][52][53]).…”
