We study the tachyon condensation of the ${\rm D}\bar{\rm D}$-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)×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… Expand
