- Question about the effects of the missing mass, lost due to the radiation of gravity waves

Hi

I have two black holes 1 Sun mass each, when they merge a significant percentage of the mass is lost and is radiated away, so the combined black hole remnant is only, say, 1.8M.

What is a behavior of the test body on an orbit far away from that binary? I assume that after some time (distance to the pair divided by c), test body would 'feel' that there is less mass inside and it would change the orbit? It is correct?

Can emitted gravitation waves be trapped on the last light orbit or fall back to the black hole?

That enourmous mass/energy loss - in what cells of metric tensor the radiated energy is hiding?

Thank you
