AdS(2) x S-7 solutions from D0-F1-D8 intersections

We study an exhaustive analytic class of massive type IIA backgrounds pre-serving sixteen real supercharges and enjoying SL(2, ) x SO(8) bosonic symmetry. The corresponding geometry is described by AdS(2) x S-7 warped over a line, which turns out to emerge from taking the near-horizon limit of D0-F1...

Zusammenfassung:We study an exhaustive analytic class of massive type IIA backgrounds pre-serving sixteen real supercharges and enjoying SL(2, ) x SO(8) bosonic symmetry. The corresponding geometry is described by AdS(2) x S-7 warped over a line, which turns out to emerge from taking the near-horizon limit of D0-F1-D8 intersections. By studying the singularity structure of these solutions we find the possible presence of localized O8/D8 sources, as well as of fundamental strings smeared over the S-7. Finally we discuss the relation between the aforementioned solutions and the known AdS(7) x S-2 class through double analytic continuation.
