后牛顿展开下三阶螺旋紧致双星运动中的自旋(1)、自旋(2)效应

Spin(1)Spin(2) Effects in the Motion of Inspiralling Compact Binaries at Third Order in the Post-Newtonian Expansion

Rafael A. Porto, Ira Z. Rothstein

摘要:

我们用有效场论方法计算了自旋-自旋和自旋-轨道效应引起的势,由此得出自旋(1)和自旋(2)对自旋致密双星运动的贡献,并给出了三阶后牛顿(PN)运动.我们使用的形式主义,使我们能够施加自旋同向性条件(SSC)在一个规范的框架中的PN扩展的所有订单。我们明确地表明与我们以前的结果,获得使用牛顿-维格纳SSC在arXiv:gr-qc/0604099和arXiv:0712.2032[gr-qc]中分别报告的自旋-自旋和自旋-轨道势的作用水平。

英文摘要:

We use effective field theory techniques to compute the potentials due to spin-spin and spin-orbit effects, from which the spin(1)spin(2) contribution to the motion of spinning compact binaries to third Post-Newtonian (PN) order follow. We use a formalism which allows us to impose the spin supplementarity condition (SSC) in a canonical framework to all orders in the PN expansion. We explicitly show the equivalence with our previous results, obtained using the Newton-Wigner SSC at the level of the action for spin-spin and spin-orbit potentials reported in arXiv:gr-qc/0604099 and arXiv:0712.2032[gr-qc] respectively.
