Post-Newtonian n-BODY Equations of the Brans-Dicke Theory
F. B. Estabrook · The Astrophysical Journal · 1969
The post-Newtonian equations of the Brans-Dicke scalar-tensor theory are derived, for the case of n gravitating point masses. They are a set of coupled second-order differential equations for the accelera- tions of the point masses, which prove to be derivable from a classical velocity-dependent Lagrangian
