Gravitomagnetic time delay and the Lense-Thirring effect in Brans-Dicke theory of gravity

TL;DR

This paper compares gravitomagnetic time delay and Lense-Thirring effects in Brans-Dicke theory with general relativity, finding that both theories predict nearly identical results within current experimental accuracy.

Contribution

It provides a theoretical comparison of gravitomagnetic effects in Brans-Dicke theory and general relativity, highlighting their experimental indistinguishability.

Findings

Both theories predict similar gravitomagnetic effects within experimental accuracy.

Current experiments cannot distinguish between Brans-Dicke and general relativity for these effects.

Theoretical predictions align closely for the phenomena studied.

Abstract

We discuss the gravitomagnetic time delay and the Lense-Thirring effect in the context of Brans-Dicke theory of gravity. We compare the theoretical results obtained with those predicted by general relativity. We show that within the accuracy of experiments designed to measure these effects both theories predict essentially the same result.
