Quark stars take significant roles while studying the behavior of strong gravitational fields and supra-nuclear territories. On the other hand, current research on the identification of both radii and masses of compact stars provides significant constraints for the equation of state (EoS) describing the stellar object of interest. Here we mainly focus our awareness on investigating the celestial features of a charged quark star in the five-dimensional (5
) form of the Einstein–Maxwell–Gauss–Bonnet (EMGB) formalism of gravity. In this context, we first obtain the governing expressions for a charged quark star represented by the MIT bag model. Subsequently, we discuss the impact of the Gauss–Bonnet (GB) Lagrangian term, which is coupled with the Einstein–Hilbert action through a coupling constant, on the fundamental physical characteristics of the celestial structure. Numerical analyses in which we discuss the dependence of energy density, pressure, and mass on radius support the existence of such a compact star. Furthermore, we show that this new type of quark star meets all the stability and feasibility conditions as well as the necessary astronomical requirements.
