Schwarzschild and linear potentials in Mannheim's model of conformal gravity
arXiv:1805.06326 · doi:10.1093/mnras/sty1286
Abstract
We study the equations of conformal gravity, as given by Mannheim, in the weak field limit, so that a linear approximation is adequate. Specializing to static fields with spherical symmetry, we obtain a second-order equation for one of the metric functions. We obtain the Green function for this equation, and represent the metric function in the form of integrals over the source. Near a compact source such as the Sun the solution no longer has Schwarzschild form. We conclude that a solution of Mannheim type cannot exist for these field equations.
