I will describe three infinite classes of analytic AdS_d solutions in massive IIA string theory, for d=7,5,4. The AdS7 solutions are conjectured to be dual to a family of (1,0)-supersymmetric CFT6’s living on an NS5-D6-D8 system. The AdS5 and AdS4 classes are dual to twisted compactifications of these (1,0) theories; their metrics and fluxes can be obtained by a simple universal map from the AdS7 ones. I will then mention an F-theoretical extension of the 6d CFT’s, which as a byproduct suggests the existence of “fractional M5-branes”.
