Abstract

We study the tachyon condensation of the DD̄-brane system with a constant tachyon vev in the context of classical solutions of the Type II supergravity. We find that the general solution with the symmetry ISO(1, p) x SO(9-p) (the three-parameter solution) includes the extremal black p-brane solution as an appropriate limit of the solution by fixing one of the three parameters (c₁). Furthermore, we compare the long distance behavior of the solution with the massless modes of the closed strings from the boundary state of the DD̄-brane system with a constant tachyon vev. We find that we must fix c₁ to zero and only two parameters are needed to express the tachyon condensation of the DD̄-brane system. This means that the parameter c₁ does not correspond to the tachyon vev of the DD̄-brane system.
