项目摘要
Within general relativity (GR) the motion of test bodies is very well described by means of the geodesic equation. This is strictly true only for structureless neutral pointlike test bodies what is justified for many physical situations and observations. However, with increasing accuracy of measurements of satellite orbits and motions of binary stars it might be possible that effects related to the internal structure of test bodies – like spin and mass multipoles – may become measurable. Such test objects with internal structure are described by means of multipolar approximation (MA) schemes. One example for such a description are the so-called Mathisson–Papapetrou–Dixon (MPD) equations. In this project we like to discuss various MA schemes in view of an identification of physical quantities. We also want to characterize possible effects related to the structure (e.g. angular momentum and the mass quadrupole) of the test bodies which may be of importance for astrophysical observations, new tests of GR and gravitational wave templates. In order to do this we like to solve the MPD equations analytically for special and numerically for more general situations.
在广义相对论(GR)中,测试物体的运动可以用测地线方程很好地描述。严格地说,这只适用于无结构的中性点状测试体,这在许多物理情况和观测中是合理的。然而,随着卫星轨道和双星运动测量精度的提高,与测试天体内部结构有关的影响----如自旋和质量多极----可能变得可以测量。这样的测试对象的内部结构描述的多极近似(MA)计划的手段。这种描述的一个示例是所谓的Mathisson-Papapetrou-狄克逊(MPD)方程。在这个项目中,我们喜欢讨论各种MA计划,鉴于识别的物理量。我们还希望表征与测试机构的结构(例如角动量和质量四极杆)相关的可能影响,这可能对天体物理观测,GR和引力波模板的新测试具有重要意义。为了做到这一点,我们喜欢解决的MPD方程解析为特殊和数值更一般的情况。
