Frame dragging by a black hole

[yanniru]

I just read in a popular magazine about the satellite to be launched in order to measure the frame dragging by a spinning earth as predicted by General Relativity. Can some one tell or give me a reference for the frame dragging expected for a black hole, either spinning or not?

Here's an easy reference from NASA (http://einstein.stanford.edu/content/lithos/VIP_Lithos-3.pdf).

From your reference I then presume that for a static black hole, the frames are also static??

If by static you mean not rotating then yes. A schwarzschild black hole would not drag frames, but any rotating massive object (like the earth) would.

By static I am also asking if the frame is fixed with respect to the event horizon, or is there inward or outward radial movement of the frame? Thanks for you patience.

Ah, you mean growing in size? I don't know of any results on that.
