  The electromagnetic radiation emitted by an accelerated charged particle can
be described theoretically as the interaction of the charge with the so-called
Fulling-Davies-Unruh thermal bath in the coordinate frame co-accelerated with
the charge. We present a similar analysis on the gravitational radiation from a
classical point mass uniformly accelerated, being pulled by a string satisfying
the weak energy condition. In particular, we derive the interaction rate (with
fixed transverse momentum) of this system of the point mass and string in the
Fulling-Davies-Unruh thermal bath in the co-accelerated frame and show that it
equals the graviton emission rate calculated in the standard method in
Minkowski spacetime.
