# Schwarzschild de sitter solution

Where can I find an elementary discussion of the orbits of particles and light rays in Schwarzschild de Sitter spacetime showing the effective radial potential, the rotational speed of circular orbits etc ?

I'm sure I can derive everything mimicking Hartle's textbook treatment of Schwarzschild-only but I need a verified source to compare notes with.

Yes exactly what I wanted, thanks! It's weird that such a comprehensive study of SdS spacetime appears so late in 1999.
