The 2PN Point-Mass N-Body Equations of Motion in Harmonic Gauge: A Computable Formulation

Hongkun Huang, Jie Yang, Wei-Tou Ni

We develop a semi-analytic and semi-numerical formulation of the harmonic-gauge second post-Newtonian (2PN) equations of motion for a general point-mass N-body system within Hadama…
