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
in the presence of the interactions between
dark energy and matter. Without the interaction, the flat universe is
observationally disfavored in this model.
