On a recently proposed scalar-tensor-vector metric extension of general relativity to explain the Pioneer anomaly

Abstract

Recently, Brownstein and Moffat proposed a gravitational mechanism to explain the Pioneer anomaly based on their scalar-tensor-vector (STVG) metric theory of gravity. In this paper we show that their model, fitted to the presently available data for the anomalous Pioneer 10/11 acceleration, is in contrast with the latest determinations of the perihelion extra-rates of Jupiter, Saturn and Uranus.
