It has been shown that generalized Einstein-Aether theories may lead to significant modifications to the non-relativistic limit of the Einstein equations. In this paper we study the effect of a general class of such theories on the Solar System. We consider corrections to the gravitational potential in negative and positive powers of distance from the source. Using measurements of the perihelion shift of Mercury and time delay of radar signals to Cassini, we place constraints on these corrections. We find that a subclass of generalized Einstein-Aether theories are compatible with these constraints.

    gr-qc 2025-05 conditional novelty 7.0 of 10

    Tensor displacement memory in Einstein-Aether gravity diverges at a critical angle when aether scalar or vector waves travel faster than tensor gravitational waves, motivating a conjecture excluding superluminal Einst...

  2. Hodge Dual Gauge Symmetry in Minimal Einstein-Aether Theory

    gr-qc 2025-04 conditional novelty 5.0 of 10

    The minimal Einstein-aether vector field is the Hodge dual of a 3-form gauge field, making the two theories equivalent and showing that divergence-free aether fields are physically trivial.
