2PN/RM gauge invariance in Brans-Dicke-like scalar-tensor theories
Olivier Minazzoli
In this note we study the 2PN/RM gauge invariance structure of a \textit{Brans-Dicke-like} Scalar-Tensor Theories (STT) without potential. Since the spherical isotropic metric play…
Extended gravity with generalized scalar field and kinetic term dependences
Tiberiu Harko, Francisco S. N. Lobo, Olivier Minazzoli
We generalize previous work by considering a novel gravitational model with an action given by an arbitrary function of the Ricci scalar, the matter Lagrangian density, a scalar fi…
New derivation of the Lagrangian of a perfect fluid with a barotropic equation of state
Olivier Minazzoli, Tiberiu Harko
In this paper we give a simple proof that when the particle number is conserved, the Lagrangian of a barotropic perfect fluid is , where $ρ…
The parameter in Brans-Dicke-like (light-)Scalar-Tensor theory with a universal scalar/matter coupling and a new decoupling scenario
Olivier Minazzoli
The post-Newtonian parameter resulting from a universal scalar/matter coupling is investigated in Brans-Dicke-like Scalar-Tensor theories where the scalar potential is assumed…
