Abstract

We study supersymmetric AdS₃ flux vacua of massive type-IIA supergravity on anisotropic G2 orientifolds. Depending on the value of the F₄ flux the seven-dimensional compact space can either have six small and one large dimension such that the external space is scale-separated and effectively four-dimensional, or all seven compact dimensions small and parametrically scale-separated from the three external ones. Within this setup we also discuss the Distance Conjecture (including appropriate D4-branes), and highlight that such vacua provide a non-trivial example of the so-called Strong Spin-2 Conjecture.
