Postpostnewtonian limit of a dilatonic gravity model
Abstract
We study a solution of the field equations for dilatonic gravity and obtain its postpostnewtonian limit. It turns out that terms to this and higher orders in the expansion may become important in strong gravitational fields, even though the postnewtonian limit coincides with that of General Relativity. This suggests that strong gravitational fields can only be studied by exact solutions of the field equations.
