On the branes behind scale-separated AdS flux vacua
Álvaro Arboleya, Adolfo Guarino, Clara Roldán-Domínguez +1
We investigate the brane origin of supersymmetric and scale-separated AdS flux vacua arising in a class of type IIB orientifold reductions with G-structure. First, using th…
7D (non-)susy vacua & DWs from dynamical open strings
Valentina Bevilacqua, Giuseppe Dibitetto, Giuseppe Sudano
Warped compactifications of massive type IIA supergravity on a 3-sphere with spacetime-filling O6/D6 sources are known to admit a half-maximal gauged supergravity description in 7D…
Open strings in type IIB AdS flux vacua
Álvaro Arboleya, Adolfo Guarino, Matteo Morittu +1
The role of open strings is investigated in the context of AdS flux vacua arising from type IIB orientifold reductions. On the one hand, contrary to expectations, the perturb…
Massive IIA flux compactifications with dynamical open strings
Juan Ramón Balaguer, Valentina Bevilacqua, Giuseppe Dibitetto +2
We consider massive type IIA compactifications down to 4 dimensions in presence of O6 planes and D6 branes parallel to them, in order to preserve half-maximal supersymmetry in 4D.…
Charge (in)stability and superradiance of Topological Stars
Andrea Cipriani, Carlo Di Benedetto, Giorgio Di Russo +2
We study linear massive scalar charged perturbations of Topological Stars in the fuzzball and in the black hole (Black String) regimes. The objects that naturally couple to the ele…
Charge instability of JMaRT geometries
Massimo Bianchi, Carlo Di Benedetto, Giorgio Di Russo +1
We perform a detailed study of linear perturbations of the JMaRT family of non-BPS smooth horizonless solutions of type IIB supergravity beyond the near-decoupling limit. In additi…
