We analyze the observational and theoretical constraints on ``Einstein-aether theory", a generally covariant theory of gravity coupled to a dynamical, unit, timelike vector field that breaks local Lorentz symmetry. The results of a computation of the remaining post-Newtonian parameters are reported. These are combined with other results to determine the joint post-Newtonian, vacuum-Cerenkov, nucleosynthesis, stability, and positive-energy constraints. All of these constraints are satisfied by parameters in a large two-dimensional region in the four-dimensional parameter space defining the theory.

Compact binary systems in Einstein-{\AE}ther gravity. II. Radiation reaction to 2.5 post-Newtonian order
The paper derives radiative equations of motion for Einstein-Aether compact binaries to 2.5PN order and reports energy-loss rates that contradict earlier flux-based calculations, with the dipole rate depending only on...

Hodge Dual Gauge Symmetry in Minimal Einstein-Aether Theory
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.
