[0909.3756] Multipolar equations of motion for extended test bodies in General Relativity

Authors: Jan Steinhoff, Dirk Puetzfeld

Date: 21 Sep 2009

Abstract: We derive the equations of motion of an extended test body in the context of Einstein's theory of gravitation. The equations of motion are obtained via a multipolar approximation method and are given up to the quadrupolar order. Special emphasis is put on the explicit construction of the so-called canonical form of the energy-momentum density. The set of gravitational multipolar moments and the corresponding equations of motion allow for a systematic comparison to competing multipolar approximation schemes.
