| contents | We present the first analysis of traversable wormhole solutions within the framework
of Einstein-aether theory. We show that the corresponding field equations admit three
distinct wormhole geometries, obtained by adopting three different classes of combinations
for the aether coupling constants. We examine the null and weak energy conditions for
three types of wormhole shape functions. Our findings reveal that, in contrast to Einstein
gravity, by choosing appropriate parameter values, wormhole geometries can satisfy the
energy conditions at the wormhole throat. We also find that in one class, wormholes
can satisfy the energy conditions not only at the wormhole throat but also throughout
the entire spacetime. Furthermore, the requirement of energy condition satisfaction,
imposes some constraints on the values of aether coupling constants. By comparing these
constraints with those previously obtained from theoretical and observational analyses,
we find that the satisfaction of energy conditions put more stringent limits on the allowed
values of the aether couplings. |
