Gravastars in f(R, G, T) gravity

The article examines the matter of gravitational vacuum stars, or gravastars, in the context of f(R, G, T) gravity, where R, G, and T refer to the Ricci Scalar, Gauss–Bonnet invariant term, and trace of energy–momentum tensor, respectively. Here, using certain suitable numerical approaches, solutions to the highly nonlinear differential equations are determined. For a well-known f(R, G, T) gravity cosmological model, the main structure of gravastars has been discussed according to core, shell, and external region. It is illustrated graphically how the relationship between mass and radius has evolved for the gravastar under consideration. (author)
