Galactic halo traversable wormhole solutions in f (G, T) gravity

This paper explores static spherically symmetric wormhole solutions in the galatic, halo region for f(G, T) gravity (G and T represent the Gauss-Bonnet invariant and trace of the energy-momentum tensor, respectively). We formulate the explicit expressions for matter variables and evaluate wormhole solutions either specifying f(G,T) model to construct shape function or taking specific form of the shape function to determine f (G, T) model. It is found that null energy condition for the effective energy momentum tensor is violated throughout the evolution in both cases while physically acceptable wormhole solutions exist only for a considered f (G, T) model.
