Cosmological model in Brans–Dicke theory of gravitation

In this paper, the Bianchi type VI cosmological model in presence of perfect fluid is investigated in Brans–Dicke [1] scalar–tensor theory of gravitation. Exact solutions of field equations are obtained by the law of Hubble parameter, as it gives constant value of deceleration parameter. Also, we studied some observational parameters such as jerk parameter, redshift, Look-back time, Luminosity distance redshift and angular diameter distance. Stability of these model is discussed with the help of the square of sound speed relation. Some physical and kinematical properties of the model are discussed.
