摘要：

A generally covariant extension of general relativity (GR) in which a dynamical unit timelike vector field is Coupled to the metric is studied in the asymptotic weak field limit of spherically symmetric static solutions. The two post-Newtonian parameters known as the Eddington-Robertson-Schiff parameters are found to be identical to those in the case of pure GR, except for some nongeneric values of the coefficients in the Lagrangian.
