Abstract:
We present results of our recent studies concerning effects of Λ > 0
in astrophysically motivated problems. Here we summarize properties of
circular geodesic motion of test particles in the equatorial plane of
Kerr-de Sitter black-hole and naked-singularity spacetimes. Along with
the standard analysis of geodesic equations of the ordinary geometry, we
introduce alternative inertial forces formalism defined within the
General Theory of Relativity in the framework of optical reference
geometry.
