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 Standard-Model Extension (SME) has been developed in order to systematically parametrize hypothetical violations of Lorentz symmetry (in the Standard Model and in the gravitational sector). In this communication, we use the latest determinations of the supplementary advances of the perihelia and of the nodes obtained by planetary ephemerides analysis to constrain SME coefficients from the pure gravity sector and also from gravity-matter couplings. Our results do not show any deviation from GR and they improve current constraints. Moreover, combinations with existing constraints from Lunar Laser Ranging and from atom interferometry gravimetry allow us to disentangle contributions from the pure gravity sector from the gravity-matter couplings.

Gravitational-wave generation in the presence of Lorentz invariance violation
Gravitational waves in a class of Lorentz-violating gravity theories would have amplitude components that do not decay with distance, strongly constraining those theories.

Modified gravitational wave propagations in linearized gravity with Lorentz and diffeomorphism violations and their gravitational wave constraints
No evidence of Lorentz or diffeomorphism violation is found in GWTC-3 gravitational waves, yielding 90% bounds on the lowest-dimension SME coefficients k(2)(I)00 and k(3)(V)jm.
