Study of self-bound anisotropic model in f(Q) gravity: An exact analytical stellar solution

This work aims to investigate the self-bound anisotropic solution for spherical objects within the [Formula: see text] gravity, where [Formula: see text] is called a nonmetric scalar. Initially, the equation of motion for gravity theory is obtained by using a linear representation of the function [Formula: see text] as [Formula: see text], here parameters [Formula: see text] and [Formula: see text] are used. Subsequently, the acquired system of differential equations was solved by including a radial metric component in conjunction with the specific ansatz of the anisotropy factor. The values of the constants required for the solution were established by using the Schwarzschild (Anti-) de Sitter exterior solution. In order to assess the physical acceptability of a solution, it is necessary to examine several physical conditions, including the behavior of pressure, density, adiabatic index, and equilibrium conditions, for different values of the parameter ‘[Formula: see text]’ inside the star system. These requirements are visually represented by graphical analysis. The current solution meets all the physical requirements, indicating that it is a suitable model of a compact stellar structure.
