Gravitational waves in massive conformal gravity

TL;DR

This paper derives plane wave solutions in massive conformal gravity, revealing seven physical modes, and demonstrates that the theory can explain binary system gravitational radiation if the graviton mass is large.

Contribution

It provides the first explicit plane wave solutions in massive conformal gravity and analyzes gravitational radiation from binaries within this framework.

Findings

Seven physical plane wave modes identified.

Large graviton mass allows binary orbit reproduction.

Theory can account for gravitational wave emission from binaries.

Abstract

First, we obtain the plane wave solution of the linearized massive conformal gravity field equations. It is shown that the theory has seven physical plane waves. In addition, we investigate the gravitational radiation from binary systems in massive conformal gravity. We find that the theory with large graviton mass can reproduce the orbit of binaries by the emission of gravitational waves.
