摘要：

In this paper, we compute the structural composition of a static spherically symmetric regime configured with anisotropic distribution in the context of f(G, T) gravity. To accomplish this, we adopt the model f(G, T) = G2 + Pi T, where denotes the coupling constant. We establish the modified field equations and utilize the MIT bag model equation of state to determine the graphical analysis of Her X-I, LMC X-4, 4U1820-30, and PSR J1614-2230 compact bodies. The Tolman IV solution is employed to study the above-mentioned structures. We check the graphical behavior of energy density, pressure components, anisotropy, and energy conditions by keeping the coupling constant fixed. We also study the behavior of mass, compactness, and redshift factors. Finally, we discuss the stability of the resulting solution through two different criteria. It is found that all the star candidates portray viable and stable behavior, except PSR J1614-2230, which is viable but not stable.
