Non-trivial tachyon profiles in low energy effective theory

We study classical solutions of a low energy effective theory of a string theory with tachyons. With a certain ansatz, we obtain all possible solutions which are static, weakly coupled and weakly curved. We find, in addition to the interpolating solutions studied in our provious paper, black hole solutions and solutions including the geometry of a capped cylinder. Some possible implications of the solutions to closed string tachyon condensation are discussed.
