FRW cosmological models with Barrow holographic dark energy in Brans-Dicke theory

Abstract

In this paper, we have generalized the behaviors of transit cosmological model under the observational data with Barrow holographic dark energy. We consider the scale factor field as φ = φ0(tβeαt)m to get exact solutions for the field equations in a non-flat FRW universe in Brans-Dicke theory. The values of the model parameters α and β are obtained by best fitting of 46 observational Hubble data (OHD) points in the range 0 ≤ z ≤ 2.36. The derived model exhibits a transition scenario for open, flat and closed universe. The EoS parameter shows a quintom-like behavior, lies both quintessence (ω >-1) and phantom (ω
