I wouldn't imagine that acceleration in itself warps space...?
Actually I take that back. A pair of neutron stars in close orbit (both
accelerating under their mutual gravity) /do/ warp space, presumably due to
their
motion.
(...I think!)
The stress energy warps space and its value is greater due to their orbital
motion
compared to them being stationary. But I don't think their acceleration
per se
contributes. In fact due to their orbital motion they will radiate away
energy as
gravity waves.
It was the gravity waves I was thinking of. That is to say, I believe very large masses
orbitting each other radiate gravity waves because of their orbital motion, hence hence
gravity waves are, or at least can be in this situation, an "acceleration-caused warping
of space" ... as per the original question.
Or have I got that wrong?
No, I think that's right. It's like EM: A charged particle causes a field. An
acceleration causes a wave in the field caused by the particle.
