We consider an Einstein-aether scalar field cosmological model where the aether and the scalar field are interacting. The model of our consideration consists of the two different interacting models proposed in the literature by Kanno et al. and Donnelly et al. We perform an extended analysis for the cosmological evolution as it is provided by the field equations by using methods from dynamical systems; specifically, we determine the stationary points and we perform a stability analysis of those exact solutions.
