2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/186632We review some aspects of the attractor mechanism for extremal black holes of (not necessarily supersymmetric) theories coupling Einstein gravity to scalars and Maxwell vector fields. Thence, we consider N=2 and N=8, d=4 supergravities, reporting some recent advances on the moduli spaces associated to BPS and non-BPS attractor solutions supported by charge orbits with non-compact stabilizers.1+12 pages, 2 figures, Contribution to the Proceedings of PASCOS 2007,13th International Symposium on Particles, Strings and Cosmology,2-7 July 2007, Imperial College, London, UK, to be published online by the American Institute of Physics; v2: minor improvements, typos fixed, Ref. addedHigh Energy Physics - Theorytext
