... This is the total gravitational mass of the system, measurable via e.g. Kepler’s third law, to order M Φ or M v 2 . Equation (32) should be familiar: it is the total rest mass of the system, corrected by the contribution of kinetic energy and the Newtonian formula for gravitational energy. But what ...
