Dark energy on higher dimensional spherically symmetric Brans-Dicke universe

In this work, we have presented a cosmological model in five dimensional spherically symmetric space-time with energy momentum tensors of minimally interacting fields of dark matter and holographic dark energy in Brans-Dicke theory. Under some realistic assumptions in consistent with the present cosmological observations, we have analyzed the field equations to obtain their exact solutions. With particular choices of the constants involved, the values of the overall density parameter and the Hubble's parameter are obtained to be very close to the latest observational values. We obtain a model universe experiencing super exponential expansion which will be increasingly dark energy dominated in the far future. A comprehensive presentation of the physical as well as kinematical aspects of the parameters, including future singularity, in comparison with the present observational findings is also provided.
