Extremal black brane attractors on the elliptic curve
Abstract
Reconsidering the analysis of the moduli space of N = 2 eightdimensional 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 pbranes (p = 0, 1, 2) with AdS_{p + 2} × S^{6  p} nearhorizon 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 pbrane charges. Then we show that the dilaton can be stabilized by the dyonic black 2brane charges.
