The Lense-Thirring effect and the Pioneer anomaly: Solar System tests
Lorenzo Iorio
TL;DR
This paper reports a precise test of the Lense-Thirring effect using Mars Global Surveyor data and examines planetary motions to evaluate if gravity explains the Pioneer anomaly, finding no supporting evidence.
Contribution
It provides the first high-precision test of the Lense-Thirring effect in the Solar System and challenges gravitational explanations for the Pioneer anomaly.
Findings
Less than 1% measurement of the Lense-Thirring effect.
Planetary motions contradict gravitational explanations for the Pioneer anomaly.
No evidence supporting gravity-based causes for the Pioneer anomaly.
Abstract
We report on a \lessim 1% test of the Lense-Thirring effect with the Mars Global Surveyor (MGS) spacecraft and on certain features of motion of Uranus, Neptune and Pluto which contradict the hypothesis that the Pioneer anomaly can be caused by some gravitational mechanism.
