A family of scalar-Einstein and vacuum Brans-Dicke axisymmetric solutions
Bertrand Chauvineau
A new method is proposed, that establishes a one to one correspondance between the whole set of static axially symmetric vacuum GR solutions and a specific class of stationary axia…
On gravitational radiation in Brans-Dicke gravity
Bertrand Chauvineau
Brans-Dicke gravity admits spherical solutions describing naked singularities rather than black holes. Depending on some parameters entering such a solution, stable circular orbits…
New views on classical and quantum Brans-Dicke theory
Júlio C. Fabris, Bertrand Chauvineau, Davi C. Rodrigues +2
The Brans-Dicke action is one of the most natural extensions of the Einstein-Hilbert action. It is based on the introduction of a fundamental scalar field that effectively incorpor…
Introducing quantum effects in classical theories
J. C. Fabris, O. F. Piattella, D. C. Rodrigues +2
In this paper, we explore two different ways of implementing quantum effects in a classical structure. The first one is through an external field. The other one is modifying the cl…
Scalar-Tensor gravity with system-dependent potential and its relation with Renormalization Group extended General Relativity
Davi C. Rodrigues, Bertrand Chauvineau, Oliver F. Piattella
We show that Renormalization Group extensions of the Einstein-Hilbert action for large scale physics are not, in general, a particular case of standard Scalar-Tensor (ST) gravity.…
Scalar-tensor theories with an external scalar
Bertrand Chauvineau, Davi C. Rodrigues, Júlio C. Fabris
Scalar-tensor (ST) gravity is considered in the case where the scalar is an external field. We show that General Relativity (GR) and usual ST gravity are particular cases of the Ex…
Visser's Massive Gravity Bimetric Theory Revisited
Alain de Roany, Bertrand Chauvineau, J. A. de Freitas Pacheco
A massive gravity theory was proposed by Visser in the late nineties. This theory, based on a backgroung metric and on an usual dynamical metric has the advantage…
Scalar-tensor propagation of light in the inner solar system at the millimetric level
Olivier Minazzoli, Bertrand Chauvineau
In a recent paper [1], motivated by forthcoming space experiments involving propagation of light in the Solar System, we have proposed an extention of the IAU metric equations at t…
Explicit form of the Scalar-Tensor metric to be used for propagation of light in the Solar system in continuity of the GR IAU2000 metric
Olivier Minazzoli, Bertrand Chauvineau
The metric recommanded by the IAU2000 resolutions allows propagation of light calculations at the c-3 level in the general relativity framework. In a recent paper [1], motivated by…
Shapiro delay of asteroids on LISA
Bertrand Chauvineau, Sophie Pireaux, Tania Regimbau
In this paper, we examine the Shapiro delay caused by the close approach of an asteroid to the LISA constellation. We find that the probability that such an event occurs at a detec…
A 2 PN/RM metric of General Relativity
Olivier Minazzoli, Bertrand Chauvineau
We present a derivation of 2PN/RM metric field equations from the Einstein field equation in General Relativity. We use the exponential parametrization and the isotropic s…
Relativistic versus Newtonian orbit model: the Relativistic Motion Integrator (RMI) software. Illustration with the LISA mission
S. Pireaux, B. Chauvineau, A. Hees
The Relativistic Motion Integrator (RMI) consists in integrating numerically the EXACT relativistic equations of motion, for a given metric (corresponding to a gravitational field…
Relativistic analysis of an earth-satellite time transfer
Olivier Minazzoli, Bertrand Chauvineau
Analytical treatment of time transfer problem for Earth-Satellite system is presented. The development was made in a complete relativistic framework. In accordance with modern cloc…
Stochastic background from extra-galactic double neutron stars
T. Regimbau, B. Chauvineau
We present Monte Carlo simulations of the extra galactic population of inspiralling double neutron stars, and estimate its contribution to the astrophysical gravitational wave back…
Relativistic analysis of the LISA long range optical links
Bertrand Chauvineau, Sophie Pireaux, Tania Regimbau +1
The joint ESA/NASA LISA mission consists in three spacecraft on heliocentric orbits, flying in a triangular formation of 5 Mkm each side, linked by infrared optical beams. The aim…
Brans-Dicke gravity and the capture of stars by black holes: some asymptotic results
Bertrand Chauvineau, Alessandro D. A. M. Spallicci, Jean-Daniel Fournier
In the context of star capture by a black hole, a new noticeable difference between Brans-Dicke theory and general relativity gravitational radiation is pointed out. This feature s…
