[1206.7087] The dynamics of the gravitational two-body problem in the post-Newtonian approximation at quadratic order in the Newton's constant

Authors: Stefano Foffa, Riccardo Sturani

Date: 29 Jun 2012

Abstract: We derive the conservative part of the Lagrangian and the energy of a gravitationally bound two-body system at fourth post-Newtonian order, up to terms quadratic in the Newton's constant. We also show that such terms are compatible with Lorentz invariance and we write an ansatz for the center-of mass position. The remaining terms carrying higher powers of the Newton constant are currently under investigation.
