Abstract

LRS Bianchi type I space time is considered to explore bulk viscous string model in modified $f (G)$ $f (G)$ gravity. Field equations are solved with some physically viable condition. It is observed that the string phase of the universe disappears. The Gauss–Bonnet invariant significantly effects on galactic fluid. The universe is expanding and isotropic at large time. Some physical parameters are also discussed in detail.
