Note on the properties of the Schwarzschild-de-Sitter spacetime
Description
The static region of the Schwarzschild-de Sitter spacetime is studied from the point of view of the optical reference geometry introduced by Abramowicz, Carter and Lasota in 1988. It is shown that in this geometry the geodesic curvature of circles r=const is independent of the parameter Λ (cosmological constant) of the spacetime. The impact of this on circular photon orbits is discussed. (author). 3 refs
