后牛顿框架下自旋计算的新进展及其应用

Recent progress in spin calculations in the post-Newtonian framework and applications

Johannes Hartung, Jan Steinhoff, Gerhard Schäfer

摘要:

最近,我们在自旋轨道和自旋(1)-自旋(2)水平上导出了紧致双星系统的次-次-首阶后牛顿哈密顿量。在这个演讲中,他们的推导将在介绍性的水平上简要概述。我们还将在演讲的第一部分讨论我们的(复杂和长)结果的一些检查。在第二部分中,我们将展示如何应用我们的结果来计算这样一个黑洞或中子星双星系统的最后稳定圆轨道。

英文摘要:

Recently we derived the next-to-next-to-leading order post-Newtonian Hamiltonians at spin-orbit and spin(1)-spin(2) level for a binary system of compact objects. In this talk the derivation of them will be shortly outlined at an introductory level. We will also discuss some checks of our (complicated and long) results in the first part of the talk. In the second part we will show how to apply our results to the calculation of the last stable circular orbit of such a binary system of black holes or neutron stars.
