Einstein-aether Theory *
Could there be an æther after all and we have just not yet noticed it? By an “æther” of course we do not mean to suggest a mechanical medium whose deformations correspond to electromagnetic fields, but rather a locally preferred state of rest at each point of spacetime, determined by some hitherto unknown physics. Such a frame would not be determined by a circumstance such as the moon’s gravita...
متن کاملStability of higher derivative modifications of Einstein - aether theory
A time-like unit vector field is used to generalize Einstein's gravity. The resulting theory, called the Einstein-aether theory, consists of a minimal coupling between an aether field and gravity. Inspired by the Bopp-Podolsky electrodynamics, which is well-known for removing the singularity at the point charge, we generalized the Einstein-aether theory by adding such a higher order self-intera...
متن کاملBlack Holes in Einstein-Aether Theory
We study black hole solutions in general relativity coupled to a unit timelike vector field dubbed the “aether”. To be causally isolated a black hole interior must trap matter fields as well as all aether and metric modes. The theory possesses spin-0, spin1, and spin-2 modes whose speeds depend on four coupling coefficients. We find that the full three-parameter family of local spherically symm...
متن کاملGödel type metrics in Einstein–aether theory
Aether theory is introduced to implement the violation of the Lorentz invariance in general relativity. For this purpose a unit timelike vector field is introduced to the theory in addition to the metric tensor. Aether theory contains four free parameters which satisfy some inequalities in order that the theory to be consistent with the observations. We show that the Gödel type of metrics of ge...
متن کاملNeutron stars in Einstein-aether theory
As current and future experiments probe strong gravitational regimes around neutron stars and black holes, it is desirable to have theoretically sound alternatives to General Relativity against which to test observations. Here we study the consequences of one such generalization, Einstein-aether theory, for the properties of non-rotating neutron stars. This theory has a parameter range that sat...
