Аннотация
We study Holographic dark energy in 5D Brans-Dicke cosmology. To investigate the stability and attractor solutions, we fit the model with the SNIa and Gamma-Ray Burst (GRB) observational data. We also examine the holographic nature of dark energy in the model through the equation of state (EoS). In addition, a reconstructed form of the EoS from holographic dark energy on the model is driven The model strongly exhibits the present cosmic accelerating. It also shows that the universe starts from an unstable radiation-dominated epoch and reaches a stable late-time accelerated phase originating from holographic dark energy in the Brans-Dicke model.
