Equations[edit]
The frame-dragging angular velocity is
and the local frame-dragging velocity relative to constant positions (the speed of light at the ergospheres)
The escape velocity (the speed of light at the horizons) relative to the local corotating ZAMO (zero angular momentum observer) is
Setting or equivalently and solving for gives the Boyer Lindquist radii of the ergospheres and setting the horizon radii, for more information see here and here
