Humpy LNRF-related orbital velocity profiles of test-particle and perfect-fluid discs in Kerr-(anti-)de Sitter spacetimes
Abstract
Humpy radial profiles of the LNRF-related orbital velocity was found for a circular motion of test particles and test perfect fluid orbiting near-extreme Kerr black holes and Kerr naked singularities. Preliminary results of an analogical study of the circular motion of test particles and fluid in the Kerr-(anti-)de Sitter spacetimes are presented.
