Particles and Fields in Kerr Spacetimes  

Light Propagation and Null Geodesics > s.a. tests of general relativity with light.
@ Light propagation: Bozza PRD(08) [optical caustics]; Jacobson CQG(11)-a1107 [circular photon orbit and ISCO]; Farooqui et al a1306 [photon polarization]; Herrera-Aguilar & Nucamendi a1506 [parameters in terms of photon red/blueshifts]; > s.a. light deflection; gravitational lensing.

Massive Particles > s.a. Carter Constant; gravitomagnetism; types of geodesics.
* Geodesics: Bound geodesic orbits can be parametrized by three constants of the motion, the (specific) orbital energy, angular momentum and the Carter constant (found by Brandon Carter in 1968 and later found to be associated with the existence of a Killing tensor by Walker and Penrose).
* Overspinning: A near-extremal Kerr black hole can be spun up beyond its extremal limit by having it capture a test particle.
* Aschenbach effect: For Kerr black holes with a spin parameter a > 0.9953, the velocity has a positive radial gradient for geodesic, stable, circular orbits in a small radial range close to the black-hole horizon.
