- 2022| World Scientific Pub...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 f ield 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<−1) regions and crosses the phantom divide. The matter and dark energy density parameters (ρD, ρm), scalar field φ and other cosmological parameters provide the results consistent with the recent observational datasets. Some other physical and geometrical behaviors of BHDE are also described and the satisfactory behaviors are found with current observations (OHD+JLA).
