In General > s.a. [black holes;
solutions with symmetries]; horizons; numerical
models [collapse].
* 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 
2(r,
):=
r2 + a2 cos2 and
(r):= r2 – 2GMr +
a2,
ds2 = 2
(dr2/ +
d2)
+ (r2+a2)
sin2 d
2– dt2 +
(2GMr/2)
(a sin2 d –
dt)2 = 
ab dxa
dxb – 
la lb
dxa dxb ,
where = 2GMr3/(r 4+a2z2),
and la = (1, (rx+ay)/(a2+y2),
(ry–ax)/(a2+y2),
z/r) is null wrt ab.
* Parameters: M represents the mass and Ma the angular momentum
measured
at infinity.
* 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–a2cos2]1/2
.
* Killing tensor: The
tensor Kab
= l(a l'b) +
r2gab [@
Ludvigsen]; > s.a. killing [Killing-Yano
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.

* 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.
