Supersymmetric solutions in three-dimensional heterotic string theory Original Research Article

We consider the low-energy effective field theory of heterotic string theory compactified on a seven-torus, and we construct electrically charged as well as more general solitonic solutions. These solutions preserve 12, 14 and 18 of N = 8, D = 3 supersymmetry and have Killing spinors which exist due to cancellation of holonomies. The associated space-time line elements do not exhibit the conical structure that often arises in 2 + 1-dimensional gravity theories.
