Brane-jet stability of non-supersymmetric AdS vacua

Understand

We classify the non-supersymmetric, and perturbatively stable within $D=4$, AdS vacua of maximal $D=4$ supergravity with a dyonic ISO(7) gauging in a large sector of the supergravity.

• Seven such vacua are established within this sector, all of them giving rise to non-supersymmetric $\textrm{AdS}_{4} \times \textrm{S}^{6}$ type IIA backgrounds with and without non-trivial warpings and with internal fluxes.
• Then, we analyse the dynamics of various probe D$p$-branes in these backgrounds searching for potential brane-jet instabilities.
• In all these cases, such instabilities are absent.
