• We analyze the AdS_3×M_7-type supersymmetric solutions, including nontrivial fluxes, of Killing spinor equations in heterotic supergravity. We classify these solutions using their Gstructures and intrinsic torsions, for the cases that the number of seven-dimensional Killing spinors N are equal to 1, 2, 3 and 4. We find that the solutions cannot have a nontrivial warp factor and the seven-dimensional manifold M_7 is characterized by G_2(SU(3))-structures for the N=1 (2) case and an SU(2)-structure for the N=3 and 4 cases. They are further classified using their nontrivial intrinsic torsions. It is shown, including the leading-order α'-corrections, that if we impose the Bianchi identities, the integrability conditions of the Killing spinor equations imply that all the field equations are satisfied.
