Static post-Newtonian limits in non-projectable Hořava-Lifshitz
gravity with an extra U(1) symmetry    [PDF]

Kai Lin, Anzhong Wang

In this paper, we study spherical static solutions in the infrared limit of the non-projectable Ho\v{r}ava-Lifshitz gravity with an extra U(1) symmetry. After obtaining such solutions, we apply them to the solar system tests, and obtain the Eddington-Robertson-Schiff parameters in terms of the coupling constants of the theory. These parameters are well consistent with observations for the physically viable coupling constants. In contrast to the projectable case, this consistence is achieved without the gauge field and Newtonian prepotential being part of the metric.
