摘要Recently, a new holographic dark energy (HDE) model with action principle was proposed [M. Li and R. X. Miao, arXiv:1210.0966]. It is the first time that the HDE model is derived from the action principle. This model completely solves the causality and circular problems in the original HDE model and automatically gives rise to a dark radiation component. Thus, it is worth investigating such an interesting model by confronting it with the current cosmological observations, so that we can check whether the model is consistent with the data and determine the regions of parameter space allowed. These issues are explored in this work. First, we investigate the dynamical behaviors and the cosmic expansion history of the model and discuss how they are related with the model parameter c. Then, we fit the model to a combination of the present Union2.1 + BAO + CMB + H-0 data. We find the model yields chi(2)(min) = 548: 798 (in a nonflat universe), comparable to the results of the original HDE model (549.461) and the concordant Lambda CDM model (550.354). At 95.4% C. L., we get 1.41 < c < 3.09 and correspondingly -2.25 < w(z = -1) < -1.39, implying the big-rip fate of the Universe at a high confidence level. Besides, for the constraints on dark radiation, we also get a rough estimation N-eff = 3.54(-0.45-0.76)(+0.32+0.67), with the central value slightly larger than the standard value 3.046.
