Thin-shell wormholes from the regular Hayward regular black hole

Department of Physics, Eastern Mediterranean University, G. Magusa, north Cyprus, Mersin 10 - Turkey(Dated: December 24, 2013)We revisit the regular black hole found by Hayward in 4-dimensional static, spherically symmetricspacetime. To nd a possible source for such a spacetime we resort to the non-linear electrodynamics(NED) in general relativity. It is found that a magnetic eld within this context gives rise to theregular Hayward black hole. By employing such a regular black hole we construct a thin-shellwormhole (TSW) for the case of various equations of state on the shell. We abbreviate a generalequation of state by p= (˙) where pis the radial pressure which is the function of the mass density(˙). In particular, a linear, logarithmic, Chaplygin, etc. forms of equations are considered. In eachcase we study the stability of the thin-shell against linear perturbations. We plot the stability regionsby tuning the parameters of the theory. It is observed that the role of the Hayward parameter is tomake the TSW more stable. The matter of our TSWs, however, remains to be exotic.
