Abstract
Certain nonasymptotically flat but supersymmetric classical solutions of type IIA supergravity can be interpreted as the infinitely boosted version of the $D$ particle solution along the $M$-theory circle. By a chain of $T$-dual transformations, this analysis also applies to yield nonasymptotically flat solutions from the asymptotically flat and (non)extremal solutions with intersecting $D$ strings and $D$ five-branes of type IIB supergravity compactified on a five-torus. Under $S$ duality, the nonasymptotically flat solutions in this context can in particular be used to describe the (1+1)-dimensional Callan-Giddings-Harvey-Strominger type black holes via spontaneous compactifications.
