## Abstract We review the concept of Sβbranes introduced by Gutperle and Strominger [1]. Using the effective spacetime description of the rolling tachyon worldsheets discussed by Sen, we analyze the possibility that the gravitational backreaction of tachyon matter is important in the timeβdependent
We study time-dependent solutions of Einstein-Maxwell gravity in four dimensions coupled to tachyon matter-the Dirac-Born-Infeld Lagrangian that provides an effective description of a decaying tachyon on an unstable D-brane in string theory. Asymptotically, the solutions are similar to the recently
