Abstract
Spatially homogeneous and anisotropic Bianchi type-I cosmological models of Brans–Dicke (BD) theory of gravitation are investigated. The model represents an accelerating universe at present and is considered to be dominated by dark energy. The cosmological constant Λ is considered as a candidate for dark energy. The derived model agrees at par with the recent SN Ia observations. We have set the BD coupling constant ω to be 40000, according to the solar system tests and evidence. We discuss various physical and geometric properties of the models and compare them with the corresponding general-relativistic models.
