Reconsidering the analysis of the moduli space of N = 2 eight-dimensional supergravity coupled to seven scalars, we propose a new scalar manifold factorization given by SO(2, 2)/(SO(2) × SO(2)) × SO(2, 1)/SO(2) × SO(1, 1). This factorization is supported by the appearance of three solutions of Type IIA extremal black p-branes (p = 0, 1, 2) with AdSp + 2 × S6 - p near-horizon geometries in eight dimensions. We analyze the corresponding attractor mechanism. In particular, we give an interplay between the scalar manifold factors and the extremal black p-brane charges. Then we show that the dilaton can be stabilized by the dyonic black 2-brane charges.
