Abstract: In this paper we study spherically symmetric single-centered attractors in (Formula presented.) supergravity in four dimensions. The attractor points are obtained by extremising the effective black hole potential in the moduli space. Both supersymmetric as well as non-supersymmetric attractors exist in mutually exclusive domains of the charge lattice. We construct axion free supersymmetric as well as non-supersymmetric multiple attractors in a simple two parameter model. We further obtain explicit examples of two distinct non-supersymmetric attractors in type IIA string theory compactified on K3 × T2 carrying D0 − D4 − D6 charges. We compute the entropy of these attractors and analyse their stability in detail. © 2014, The Author(s).
