This paper investigates the influence of charge on physical features of gravastars in the framework of energy-momentum squared gravity. A gravastar is an alternate model to a black hole that comprises of three distinct regions, namely the intermediate shell, inner and outer sectors. Different values of the barotropic equation of state parameter provide the mathematical formulation for these regions. We construct the structure of a gravastar admitting conformal motion for a specific model of energy-momentum squared gravity. The field equations are formulated for a spherically symmetric spacetime with charged perfect matter distribution. For the smooth matching of external and internal spacetimes, we use Israel matching criteria. Various physical attributes of gravastars such as the equation of state parameter, proper length, entropy and energy are investigated (in the presence of charge) versus thickness of the shell. The charge in the inner core of gravastars preserves the state of equilibrium by counterbalancing the inward gravitational force. It is concluded that the non-singular solutions of charged gravastar are physically viable in the background of energy-momentum squared gravity.

This paper studies the influence of charge on a compact stellar structure also regarded as vacuum condensate star in the background of f (R, T 2 ) gravity. This object is considered the alternate of black hole whose structure involves three distinct regions, i.e., interior, exterior and thin-shell. We analyze these domains of a gravastar for a particular model of this modified theory. In the inner region of a gravastar, the considered equation of state defines that energy density is equal to negative pressure which is the cause of repulsive force on the spherical shell. In the intermediate shell, pressure and energy density are equal and contain ultra-relativistic fluid. The inward-directed gravitational pull of thin-shell counterbalance the force exerted by the inner region of a gravastar allowing the formation of a singularity-free object. The Reissner-Nordstrom metric presents the outer vacuum spherical domain. Moreover, we discuss the impact of the charge on physical attributes of a gravastar such as the equation of state parameter, entropy, proper length and energy. We conclude that singularityfree solutions of charged gravastar are physically consistent in this modified theory.
