S-wave sector of type IIB supergravity onS1×T4

We consider type IIB supergravity in ten dimensions compactified on $S^1\times T^4$, with intersecting one and five $D$-branes in the compact dimensions. By imposing spherical symmetry in the resulting five-dimensional theory, we further reduce the $s$-wave sector of the theory to a two-dimensional dilaton gravity. Via this construction, the techniques developed for the general two-dimensional dilaton gravities are applicable in this context. Specifically, we obtain the bosonic sector general static solutions. In addition to the well-known asymptotically flat black hole solutions, they include solutions with naked singularities and nonasymptotically flat black holes.
