Radial motion of a spinning test body in the field of a black hole
The gravitational radiation emitted by a test particle falling radially into a Schwarzchild black hole has been analyzed by Zerilli. Here we investigate the effect of assigning spin to both the test particle and the source. We find that more (less) gravitational radiation is emitted if the spins are antiparallel (parallel). © 1972 The American Physical Society.
