Instabiler Orbit auf r=2, SL und kosmische Parameter: M=1, a=9/10, ℧=2/5, Λ=1/9. Simulator Code siehe unten, für mehr Details klick aufs Bild:

Getrennte Darstellung der Horizonte und Ergosphären (hier eher Ergokuppeln/Ergodome), Parameter wie im Bild oben. Die Fluchtgeschwindigkeit vESC ist relativ zu lokalen ZAMOs, und die Frame Dragging Geschwindigkeit vFD der ZAMOs relativ zu fixen {r,θ,φ} bzw. {x,y,z} Positionen:

Gallerie für verschiedene positive und negative Λ, wobei die Parameter des schwarzen Lochs M=1, a=9/10, ℧=2/5, Θ=85°gleich bleiben; für die Anzeige der Werte für H bzw. Λ, höhere Auflösung und den Vergleich mit Schwarzschild De Sitter (SSdS, a=℧=0) klick auf die Bilder:

Der Simulator für die Bahnen von Photonen, geladenen und neutralen Partikeln läuft wahlweise in Boyer Lindquist (crd=1) und Kerr Schild (crd=2) Koordinaten (letztere für horizontüberschreitende Bahnen), die Anzeige der lokalen Geschwindigkeit im Display ist relativ zu ZAMOs:
