Bayesian test of Brans-Dicke theories with planetary ephemerides: Investigating the strong equivalence principle
Vincenzo Mariani, Olivier Minazzoli, Agnès Fienga +2
Context: We are testing the Brans-Dicke class of scalar tensor theories with planetary ephemerides. Aims: In this work, we apply our recently proposed Bayesian methodology to the B…
Bayesian test of the mass of the graviton with planetary ephemerides
Vincenzo Mariani, Agnès Fienga, Olivier Minazzoli +2
In this work, we investigated Bayesian methodologies for constraining in the Solar System a Yukawa suppression of the Newtonian potential -- which we interpret as the effect of a n…
Viscosity contrasts in the Venus mantle from tidal deformations
Christelle Saliby, Agnes Fienga, Arthur Briaud +2
The tidal deformations of a planet are often considered as markers of its inner structure. In this work, we use the tide excitations induced by the Sun on Venus for deciphering the…
Testing the mass of the graviton with Bayesian planetary numerical ephemerides B-INPOP
Vincenzo Mariani, Agnès Fienga, Olivier Minazzoli
We use MCMC to sample the posterior distribution of the mass of the graviton -- assumed here to be manifest through a Yukawa suppression of the Newtonian potential -- by using INPO…
Testing Theories of Gravity with Planetary Ephemerides
Agnès Fienga, Olivier Minazzoli
We describe here how planetary ephemerides are built in the framework of General Relativity and how they can be used to test alternative theories. We focus on the definition of the…
Interplanetary Laser Tri-lateration Network: simulation with INPOP planetary ephemerides
Agnès Fienga
This study is done in the context of the project titled Interplanetary Laser Tri-lateration Network (ILTN) proposed by \cite{2018P&SS..153..127S} and investigated more in details b…
Constraints on the lunar core viscosity from tidal deformation
Arthur Briaud, Agnès Fienga, Daniele Melini +8
We use the tidal deformations of the Moon induced by the Earth and the Sun as a tool for studying the inner structure of our satellite. Based on measurements of the degree-two tida…
Constraining massless dilaton theory at Solar system scales with the planetary ephemeris INPOP
L. Bernus, O. Minazzoli, A. Fienga +5
We expose the phenomenology of the massless dilaton theory in the Solar system for a non universal quadratic coupling between the scalar field which represents the dilaton, and the…
