Anisotropic stellar modeling via MIT Bag model EoS admitting Finch–Skea spacetime in f(Q) gravity
This study evaluates the viability and stability of anisotropic compact stellar objects by utilizing the Finch–Skea spacetime solutions in f(Q) gravity, where Q is a nonmetricity scalar that incorporates gravitational effects. The physical properties of the compact star EXO 1785-248 are investigated by employing a static spherical metric in the inner region and Schwarzschild spacetime in the outer region. The unknown parameters are determined using observed values of the radius and mass of the studied compact star. The suggested mass and radius values of EXO 1785-248 from existing literature are utilized. Subsequently, calculations are conducted to determine the essential features of the compact star and establish its stability and physical existence. Various aspects are analyzed, including energy density, pressure profiles, gradients, anisotropic factors, energy conditions, sound speeds, Tolman–Oppenheimer–Volkoff forces, equation of state components, mass function, compactification, and redshift, in order to achieve this objective.
