AdS8 solutions in type II supergravity

Abstract

Abstract We find non-supersymmetric AdS8 solutions of type IIA supergravity. The internal space is topologically an S 2 with a U(1) isometry. The only non-zero flux is F 0; an O8 sourcing it is present at the equator of the S 2. The warping function and dilaton are non-constant. It is also possible to add D8-branes on top of the O8. Possible destabilizing brane bubbles (whose presence would be suggested by the weak-gravity conjecture) are either absent or collapsing. Our solutions are candidate holographic duals to unitary interacting CFTs in seven dimensions with exceptional global symmetry. We also present analogous non-supersymmetric AdS d solutions for general d which are supported only by F 0.
