Findings

Two families of smooth solutions including known and new nullbranes.

Explicit construction of all classified solutions.

Analysis of U-duality orbits of these backgrounds.

Abstract

We classify generalised supersymmetric fluxbranes in type II string theory obtained as Kaluza-Klein reductions of the Minkowski space vacuum of eleven-dimensional supergravity. We obtain two families of smooth solutions which contains all the known solutions, new solutions called nullbranes, and solutions interpolating between them. We explicitly construct all the solutions and we study the U-duality orbits of some of these backgrounds.
