We consider compactifications of massive IIA supergravity on a six-sphere. This setup is known to give rise to non-supersymmetric AdS 4 vacua preserving SO(7) as well as G 2 residual symmetry. Both solutions have a round S 6 metric and are supported by the Romans’ mass and internal F 6 flux. While the SO(7) invariant vacuum is known to be perturbatively unstable, the G 2 invariant one has been found to have a fully stable Kaluza-Klein spectrum. Moreover, it has been shown to be protected against…
