Abstract

We review some recent results about exact classical solutions in string theory. In particular, we consider four dimensional extremal electric black holes which are related via dimensional reduction to the exact five dimensional fundamental string solutions. We also comment on the issue of \a' corrections to non-extremal black holes. (To appear in Proceedings of the Conference on Current Topics in Astrofundamental Physics, September 1994, Erice)
