J. Blümlein, A. Maier, P. Marquard, G. Schäfer

摘要:

在低速和弱相互作用条件下,用后牛顿展开精确描述了早期内旋相的双源引力波。我们使用非相对论性有效场论计算了五阶和部分六阶的保守动力学。我们给中央观测值的预测,并确定所需的系数的建设一个有效的单体哈密顿量,扩展我们的结果的适用性,后期的螺旋和合并阶段。

英文摘要:

Binary sources of gravitational waves in the early inspiral phase are accurately described by a post-Newtonian expansion in small velocity and weak interaction. We compute the conservative dynamics to fifth and partial sixth order using a non-relativistic effective field theory. We give predictions for central observables and determine the required coefficients for the construction of an Effective One-Body Hamiltonian, extending the applicability of our results to the late inspiral and merger phases.
