TY - JOUR ID - 76302 AU - Slaný, Petr PY - 2023 TI - Test particle motion along equatorial circular orbits in the revisited Kerr-de Sitter spacetime JF - Physical Review D VL - 108 IS - 8 SP - "084026-1"-"084026-9" EP - "084026-1"-"084026-9" SN - 24700010 KW - test particle KW - equatorial circular orbits KW - kerr de Sitter spacetime UR - https://journals.aps.org/prd/abstract/10.1103/PhysRevD.108.084026 N2 - Both circular and epicyclic motion of test particles along equatorial circular orbits in the revisited Kerrde Sitter spacetime are analyzed. We present relations for specific energy, specific angular momentum, and Keplerian angular velocity of particles on equatorial circular orbits, and discuss criteria for the existence and stability of such orbits giving limits on spacetime parameters. Finally, we discuss the epicyclic motion along equatorial circular orbits obtaining relations for radial and vertical epicyclic frequencies. The results are compared with those for standard Kerr-de Sitter geometry. ER -
