“…Additionally, there is an increasing risk of introducing multiple correlations between the parameters of the theory, as well as between these parameters and those of the solar system (i.e., masses). Given that it can take up to eight hours of computation to adjust the solar system parameters of the ephemeris at a single point in the parameter space (Mariani et al 2023), achieving a densely filled parameter space becomes highly computationally demanding if the parameter space dimension is greater than one. Moreover, the statistical methodology also grows more complex with an increase in the number of parameters to constrain.…”

“…The results of these investigations are given on Table 7. Bernus et al (2019Bernus et al ( , 2020 had used a method of random walk exploration that is more conservative that the Monte Carlo Markov Chain (MCMC) algorithm used by Mariani et al (2023). With the same random walk exploration method, but using the updated INPOP21a ephemerides, Mariani et al (2023) obtained a constraint that is 3 times smaller than Bernus et al (2020).…”

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 reference frame (space and time) in which the planetary ephemeris is described, the equations of motion that govern the orbits of solar system bodies and electromagnetic waves. After a review on the existing planetary and lunar ephemerides, we summarize the results obtained considering full modifications of the ephemeris framework with direct comparisons with the observations of planetary systems, with a specific attention for the PPN formalism. We then discuss other formalisms such as Einstein-dilaton theories, the massless graviton and MOND. The paper finally concludes on some comments and recommendations regarding misinterpreted measurements of the advance of perihelia.

“…Theorists usually regard very light and gravitationally coupled Brans-Dicke scalars as poison rather than catnip because of the strong observational constraints they must satisfy, such as from precision measurements within the solar system [2,[25][26][27][28][29][30][31][32][33][34]. In particular solar system tests constrain the post-Newtonian deviations from the metric predicted by GR -including those due to a Brans-Dicke scalar -to be at most of order 10 −5 [35] (see [36] for a careful treatment of ephemerides when placing such constraints).…”

Scalar-tensor theories with the shift symmetries required by light scalars are well-explored modifications to GR. For these, two-derivative scalar self-interactions usually dominate at low energies and interestingly compete with the two-derivative metric interactions of GR itself. Although much effort has been invested in single scalars (on grounds of simplicity) these happen to have no two-derivative interactions, requiring such models to explore higher-derivative interactions (that usually would be less important at low-energies). This suggests multiple-scalar sigma models as well-motivated candidates for finding new phenomena in tests of gravity. We identify a new multi-field screening mechanism appropriate for two light scalar fields (an axion and a Brans-Dicke style dilaton) that relies on their mutual two-derivative interactions. We show how very weak axion-matter couplings can introduce axion gradients that can reduce the apparent coupling of the Brans-Dicke scalar to macroscopic matter sources. We further identify a relaxation mechanism that allows this reduction to be amplified to a suppression by the ratio of the axion gradient's length scale to the source's radius (similar in size to the suppression found in Chameleon models). Unlike some screening mechanisms our proposal is technically natural and works deep within the regime of control of the low-energy EFT. It uses only ingredients that commonly appear in the low-energy limit of string vacua and so is likely to have wider applications to models that admit UV completions. We briefly discuss phenomenological implications and challenges for this scenario, which suggests re-examination of decay loss bounds and the value of equivalence-principle tests for different-sized objects.

“…The data has also been used to obtain constraints on the local DM and cosmic neutrino densities [148]. Planetary ephemerides released by the Observatory of Paris and the Co te d'Azur Observatory (INPOP) [158,159] have also been used to constrain fifth-force ranges [160] and the effects of a finite graviton mass [161].…”

Using the OSIRIS-REx mission and ground-based tracking data for the asteroid Bennu, we derive new constraints on fifth forces and ultralight dark matter. The bounds we obtain are strongest for mediator masses $m \sim 10^{-18} - 10^{-17}\,{\rm eV}$, where we currently achieve the tightest bounds. Our limits can be translated to a wide class of models leading to Yukawa-type fifth forces, and we demonstrate how they apply to $U(1)_B$ dark photons and baryon-coupled scalars. Our results demonstrate the potential of asteroid tracking in probing well-motivated extensions of the Standard Model and ultralight dark matter satisfying the fuzzy dark matter constraints.
