Scenario of the Universe with Bulk Viscosity & Massive Strings in Saez-Ballester Theory

Abstract

Spatially homogeneous and anisotropic Bianchi type-V cosmological models have been investigated in presence of bulk viscosity and massive strings in the light of scalar tensor theory of gravitation proposed by Saez and Ballester (Phys. Lett. A 113, 467; 1986). Some exact solutions of modified field equations have been obtained with the help of three physically apt assumptions. Physical and kinematical features of the models are discussed in detail. We also discussed Statefinder parameters for the models and found that their values agree with ΛCDM dynamics. We observe that the models are in accordance with recent observations.
