We describe the geometry of all type II common sector backgrounds with two supersymmetries. In particular, we determine the spacetime geometry of those supersymmetric backgrounds for which each copy of the Killing spinor equations admits a Killing spinor. The stability subgroups of both Killing spinors are Spin(7)8, SU(4)8 and G2 for IIB backgrounds, and Spin(7), SU(4) and G28 for IIA backgrounds. We show that the spacetime of backgrounds with spinors that have stability subgroup K8 is a pp… CONTINUE READING
