New constraints on Saturn's interior from Cassini astrometric data
Valéry Lainey, Robert A. Jacobson, Radwan Tajeddine +15
Using astrometric observations spanning more than a century and including a large set of Cassini data, we determine Saturn's tidal parameters through their current effects on the o…
Scaling laws to quantify tidal dissipation in star-planet systems
Pierre Auclair-Desrotour, Stéphane Mathis, Christophe Le Poncin-Lafitte
Planetary systems evolve over secular time scales. One of the key mechanisms that drive this evolution is tidal dissipation. Submitted to tides, stellar and planetary fluid layers…
Testing Lorentz symmetry with planetary orbital dynamics
Aurélien Hees, Quentin G. Bailey, Christophe Le Poncin-Lafitte +6
Planetary ephemerides are a very powerful tool to constrain deviations from the theory of General Relativity using orbital dynamics. The effective field theory framework called the…
Tests of gravitation with Gaia observations of Solar System Objects
A. Hees, D. Hestroffer, C. Le Poncin-Lafitte +1
In this communication, we show how asteroids observations from the Gaia mission can be used to perform local tests of General Relativity (GR). This ESA mission, launched in Decembe…
Scaling laws to understand tidal dissipation in fluid planetary regions and stars I - Rotation, stratification and thermal diffusivity
P. Auclair-Desrotour, S. Mathis, C. Le Poncin-Lafitte
Tidal dissipation in planets and stars is one of the key physical mechanisms driving the evolution of star-planet and planet-moon systems. Several signatures of its action are obse…
