Abstract

We extend our previous analysis and consider the interacting holographic Ricci dark energy (IRDE) model in non-flat universe. We study astrophysical constraints on this model using the recent observations including the type Ia supernovae (SNIa), the baryon acoustic oscillation (BAO), the cosmic microwave background (CMB) anisotropy, and the Hubble parameter. It is shown that the allowed parameter range for the fractional energy density of the curvature is 0.005-0.005 \lesssim Ωk0\Omega_{k0} \lesssim 0.0150.015 in the presence of the interactions between dark energy and matter. Without the interaction, the flat universe is observationally disfavored in this model.
