Sumario: | In this review I discuss various aspects of some of the recently constructed black hole and soliton solutions in string theory. I begin with the axionic instanton and related solutions of bosonic and heterotic string theory. The latter ten-dimensional solutions can be compactified to supersymmetric monopole, string and domain wall solutions which break 1/2 of the spacetime supersymmetries of N=4, D=4 heterotic string theory, and which can be generalized to two-parameter charged black hole solutions. The low-energy dynamics of these solutions is also discussed, as well as their connections with strong/weak coupling duality and target space duality in string theory. Finally, new solutions are presented which break 3/4, 7/8 and all of the spacetime supersymmetries and which also arise in more realistic N=1 and N=2 compactifications. |
