On the Equation of Motion for a Fast Moving Small Object in the Strong Field Point Particle Limit
Takashi Fukumoto, Toshifumi Futamase, Yousuke Itoh
Abstract
We give a straightforward and divergence free derivation of the equation of motion for a small but finite object in an arbitrary background using strong field point particle limit. The resulting equation becomes a generalized geodesic for a non-rotating spherical object which is consisitent with previous studies.
