Annotation

Electrically charged dust is considered in the framework of Einstein– Maxwell–dilaton gravity with a Lagrangian containing the interaction term P(χ)Fμν Fμν, where P(χ) is an arbitrary function of the dilaton scalar field χ, which can be normal or phantom. Without assumption of spatial symmetry, we show that static configurations exist for arbitrary functions g00 = exp(2γ (xi )) (i = 1, 2, 3) and χ = χ(γ ). If χ = const, the classical Majumdar–Papapetrou (MP) system is restored. We discuss solutions that represent black holes (BHs) and quasi-black holes (QBHs), deduce some general results and confirm them by examples.
