Does phantom energy produce black hole ?

We have found an exact solution of spherically symmetrical Einstein equations describing a black hole with a special type phantom energy source. It is surprising to note that our solution is analogous to Reissner-Nordström black hole. Recent astrophysical observations have confirmed that the Universe at present is expanding with an acceleration. It is proposed that this unexpected cosmological behavior is caused by a hypothetical dark energy with a positive energy density and a negative pressure. The matter with the property, energy density ρ > 0 but pressure p < 0 has been denoted 'phantom energy'. Several authors have recently discussed accelerating phase of the Universe by using phantom energy as source [1-8]. Since traversable Wormholes require so called exotic matter with a negative pressure p < 0 , some authors have recently investigated the physical properties and characteristic of traversable Wormholes by taking phantom energy as source [ 9-13]. In this article, we present a black hole solution with special type phantom energy as a source. By choosing the parameters adequately , the solution coincides with Reissner-Nordström black hole solution. Before discussing this surprising result, we proceed to show the solution.
