Gravitational dipole radiations from binary systems

TL;DR

This paper explores the potential for significant gravitational dipole radiation in relativistic gravity theories and discusses how binary star systems can be used to detect or constrain such effects.

Contribution

It introduces a framework for analyzing dipole radiation in alternative gravity theories and derives constraints on gravitational couplings beyond general relativity.

Findings

Dipole radiation could be detectable in certain relativistic gravity models.

Binary star orbital decay provides a means to test these theories.

Constraints on non-GR gravitational couplings are established.

Abstract

We investigate the possibility of generating sizeable dipole radiations in relativistic theories of gravity. Optimal parameters to observe their effects through the orbital period decay of binary star systems are discussed. Constraints on gravitational couplings beyond general relativity are derived.
