Testing Gravitation in the Solar System with Radio Science experiments
A. Hees, P. Wolf, B. Lamine +5
The laws of gravitation have been tested for a long time with steadily improving precision, leading at some moment of time to paradigmatic evolutions. Pursuing this continual effor…
Light Deflection for relativistic space astrometry in closed form
Stefano Bertone, Christophe Le Poncin-Lafitte
Given the extreme accuracy reached by future global space astrometry, one needs a global relativistic modeling of observations. A relativistic definition of astrometric observables…
Accretion of Saturn's mid-sized moons during the viscous spreading of young massive rings: solving the paradox of silicate-poor rings versus silicate-rich moons
Sébastien Charnoz, Aurélien Crida, Julie C. Castillo-Rogez +7
The origin of Saturn's inner mid-sized moons (Mimas, Enceladus, Tethys, Dione and Rhea) and Saturn's rings is debated. Charnoz et al. (2010) introduced the idea that the smallest i…
Radioscience simulations in General Relativity and in alternative theories of gravity
Aurelien Hees, Peter Wolf, Brahim Lamine +6
In this communication, we focus on the possibility to test GR with radioscience experiments. We present a new software that in a first step simulates the Range/Doppler signals dire…
