英文摘要 | We consider a brane cosmological model with energy exchange between the brane and the bulk. Parametrizing the energy exchange term using the scale factor and Hubble parameter, we are able to exactly solve the modified Friedmann equation on the brane. In this model, the equation of state for the effective dark energy has a transition behaviour, changing from w(de)(eff) > - 1 to we(de)(eff) < - 1, while the equation of state for the dark energy on the brane has w > - 1. Fitting data from type Ia supernovae, the Sloan Digital Sky Survey and the Wilkinson Microwave Anisotropy Probe, our universe is predicted now to be in a state of super-acceleration with w(de0)(eff) = -1.21. |
