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. |
