Properties of the Reissner-Nordström spacetimes with a nonzero cosmological constant

Popis výsledku v původním jazyce

Properties of the Reissner-Nordström black-hole and naked-singularity spacetimes with a nonzero cosmological constant are represented by their geodetical structure and embedding diagrams of the central planes of both the ordinary geometry and associatedoptical reference geometry. Both the asymptotically de Sitter and anti-de Sitter spacetimes are considered and compared with the asymptotically flat spacetimes. Motion of test particles (timelike geodesics for uncharged particles) and photons (null geodesics) is described in terms of an appropriate "effective potential". Circular geodesics are discussed and photon escape cones determined. The spacetimes are divided in their parameter space into separated parts according to different character of the effective potential and properties of the circular geodesics. In all asymptotically anti-de Sitter black-hole spacetimes and some asymptotically de Sitter black-hole spacetimes a region containing stable circular geodesics exists, which allo
