Stellar structure in a Newtonian theory with variable $G$

Júlio C. Fabris, Túlio Ottoni, Júnior D. Toniato +1

A Newtonian-like theory inspired by the Brans-Dicke gravitational Lagrangian has been recently proposed. For static configurations the gravitational coupling acquires an intrinsic…

Post-Newtonian $γ$ -like parameters and the gravitational slip in scalar-tensor and $f (R)$ theories

Júnior D. Toniato, Davi C. Rodrigues

We review the fundamentals and highlight the differences between some commonly used definitions for the PPN gamma parameter ( $γ$ ) and the gravitational slip ( $η$ ). Here we stress t…
