摘要: We investigate the propagation of gravitational waves in context fourth order gravity nonminimally coupled to a massive scalar field. Using damping orbital period coalescing stellar binary systems, we impose constraints on free parameters extended models. In particular, find that variation is function three mass scales which depend model under consideration; can constrain these from current observational data.
