Show affiliationsWe study dynamical behaviors of dark energy models interacting with dark matter and unparticle in the standard flat Friedmann–Robertson–Walker cosmology. We considered four different interacting models and examined the stability of the critical points. We find that there exist late-time scaling attractors corresponding to an accelerating universe, and the alleviation of the coincidence problem depends on the choice of parameters in the models.
