Anisotropic compact stars admitting karmarkar condition in f(Q) theory

The major goal of this study is to examine the viability and stability of anisotropic compact stellar objects using the Karmarkar condition in f(Q) gravity, where Q is a scalar of nonmetricity that explains gravitational effects. We consider a static spherical metric in inner and Schwarzschild spacetime in outer regions of the star to analyze the physical attribute of Vela X - 1, SAX J 1808.4- 3658, 4U 1608- 52, PSR J0348+0432 and 4U 1820- 30 compact stars. The unknown parameters are determined through observational values of the radius and mass of the considered compact stars. We take a specific model of this theory to evaluate the energy density, pressure elements, anisotropy, equation of state parameters and energy bounds in inner region of suggested stellar objects. The equilibrium position of these stars is examined through Tolman-Oppenheimer-Volkoff equation and their stability checked by Herrera cracking method and adiabatic index. We find more viable as well as stable compact stars in this modified theory.
