广义相对论中扩展试验体的多极运动方程

Multipolar equations of motion for extended test bodies in General Relativity

Jan Steinhoff, Dirk Puetzfeld

摘要:

我们在爱因斯坦引力理论的背景下导出了扩展的测试体的运动方程。通过多极近似方法得到的运动方程,并给出了四极阶。特别强调的是明确建设的所谓的能量动量密度的标准形式。引力多极矩和相应的运动方程组允许竞争多极近似计划进行系统的比较。

英文摘要:

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.
