Title | Probing scalar-tensor theories with compact binaries |
Abstract | Until now, observations and experiments have confirmed General Relativity (GR) as the best theory of gravity. The current gravitational wave interferometers, LIGO and Virgo, as well as the future space-based detector LISA, will permit to challenge further GR in the highly dynamical and strong field regime of gravity. In this talk, I will focus on alternative theories with an additional scalar degree of freedom, in relation to compact objects. In particular, I will describe the evolution of compact binary systems in these theories using the post-Newtonian formalism. I will show that one of the most interesting phenomenological consequence lies in finite-size effects. |
