Two new classes of solutions of the d = 11 supergravity equations are obtained in which the internal space is a U(1) bundle over a six-dimensional Kaehler manifold. The 4-index field strength is nonzero both in space-time and in the internal space.
The divergent part of the self force of a radiating string coupled to gravity, an antisymmetric tensor and a dilaton in four dimensions are calculated to first order in classical perturbation theory. While this divergence can be absorbed into a renormalization of the string tension, demanding that both it and the divergence in the energy momentum tensor vanish forces the string to have the couplings of compactified N = 1 D = 10 supergravity. In effect, supersymmetry cures the classical infinities.
