The Higher Dimensional Gravastars

Abstract

A new model of gravastar is obtained in D-dimensional Einstein gravity. This class of solutions includes the gravastar as an alternative to D-dimensional versions of the Schwarzschild-Tangherlini black hole. The configuration of this new gravastar consists of three different regions with different equations of state: [I] Interior: 0 ≤ r < r1, ρ = − p; [II] Shell: r1 ≤ r < r2, ρ = p; [III] Exterior: r2 < r, ρ = p = 0. The outer region of this gravastar corresponds to a higher dimensional Schwarzschild-Tangherlini black hole.
