Equatorial circular orbits in the Kerr-de Sitter spacetimes
arXiv:gr-qc/0307049 · doi:10.1103/PhysRevD.69.064001
Abstract
Equatorial motion of test particles in the Kerr-de Sitter spacetimes is considered. Circular orbits are determined, their properties are discussed for both the black-hole and naked-singularity spacetimes, and their relevance for thin accretion discs is established.
