Kerr Solutions |
In General
> s.a. black holes; solutions with
symmetries; particles and fields [including geodesics].
* Idea: A two-parameter family of
solutions to Einstein's equation, representing (the only) stationary vacuum black-hole solutions.
* Line element: In Boyer-Lindquist coordinates,
with ρ2(r,θ):=
r2
+ a2 cos2θ
and Δ(r):= r2 − 2GMr
+ a2,
ds2 = ρ2 (dr2/Δ + dθ2) + (r2+a2) sin2θ dφ2− dt2 + (2GMr/ρ2) (a sin2θ dφ − dt)2 = ηab dxa dxb − λ la lb dxa dxb ,
where λ = 2GMr3/(r
4+a2z2),
and la
= (1, (rx+ay)/(a2+y2),
(ry−ax)/(a2+y2),
z/r) is null with respect to ηab;
> s.a. Kerr-Schild Solutions.
* Parameters: M represents the mass
and Ma the angular momentum measured at infinity; Extremal solutions have a = GM.
* Inequalities: The three parameters
that characterize the Kerr black hole (M, a and horizon area) satisfy
several important inequalities, some of which remain valid also for dynamical black holes;

* Singularities and horizons:
They have a singularity at r = 0, horizons
at r = r±, and
an ergosurface at r = r0, where
r± = GM ± [(GM)2 − a2]1/2 , r0 = GM + [(GM)2 − a2 cos2θ]1/2 .
* Killing tensor:

* Boyer-Lindquist coordinates:
A coordinate system that allows to maximally extend the Kerr solution.
* Light-like limit: The
gravitational field relative to a distant observer moving at high speed
rectilinearly in an arbitrary direction is an impulsive plane gravitational
wave with a singular point on its wave front.
