Title: Tests of modified gravity theories in the Solar System12.
Authors: Mozaffari, Ali

Subjects: Solar gravity, Solar system, Newtonian cosmology, Numerical analysis, LISA Pathfinder
Abstract (English): We review the case for testing preferred acceleration scale theories of gravity (sometimes falling under the guise of modified Newtonian dynamics) in the Solar System using the forthcoming LISA Pathfinder (LPF) mission. Using a combination of analytical and numerical results, we suggest that different types of theory should be detectable using the predicted anomalous tidal stresses effects around the saddle points of the Newtonian gravitational field. The saddle point bubbles' expected extent of ∼400 km are to be contrasted with potential miss parameters of ≤10 km, making such a test in easy reach of LPF. We also consider routes to constraining our theories from data, based on scenarios of both null and positive results. [ABSTRACT FROM AUTHOR]
Abstract (French): Nous passons en revue la possibilité de tester des théories de la gravité avec échelle d'accélération préférentielle (parfois dans la famille de la dynamique newtonienne modifiée ou MOND) dans le système solaire en utilisant la mission prochaine LISA Patfinder (LPF). Utilisant une combinaison de résultats analytiques et numériques, nous suggérons que nous devrions pouvoir sonder différents types de théories à partir des effets de marée anomaux prédits autour du point selle du champ de gravité newtonien. Les bulles au voisinage du point selle, attendues à une amplitude ∼400 km, contrastent avec les paramètres de lacune de potentiel de portée ≤10 km, ce qui en fait un test facile pour LPF. Nous envisageons aussi d'autres scénarios pour contraindre nos théories à partir des données, que les résultats soient nuls ou positifs. [Traduit par la Rédaction] [ABSTRACT FROM AUTHOR]
