Orbits and attractors for image Maxwell–Einstein supergravity theories in five dimensions Original Research Article

BPS and non-BPS orbits for extremal black-holes in image Maxwell–Einstein supergravity theories (MESGT) in five dimensions were classified long ago by the present authors for the case of symmetric scalar manifolds. Motivated by these results and some recent work on non-supersymmetric attractors we show that attractor equations in image MESGTs in image do indeed possess the distinct families of solutions with finite Bekenstein–Hawking entropy. The new non-BPS solutions have non-vanishing central charge and matter charge which is invariant under the maximal compact subgroup image of the stabilizer image of the non-BPS orbit. Our analysis covers all symmetric space theories image such that G is a symmetry of the action. These theories are in one-to-one correspondence with (Euclidean) Jordan algebras of degree three. In the particular case of image MESGT with scalar manifold image a duality of the two solutions with regard to image and image supergravity is also considered.
