Our manuscript aims to analyze the viability and stability of anisotropic stellar objects in the modified symmetric teleparallel gravity.A particular model of this extended theory is considered to formulate explicit field equations that govern the interaction between matter and geometry.The configuration of static spherical symmetric structures is examined through the Finch-Skea solution.However,the values of unknown constants in the metric potentials are evaluated by the Darmois junction conditions.For the viability of the proposed stellar objects,physical parameters including density,pressure,anisotropy,mass,energy constraints,compactness function,and redshift are analyzed.Furthermore,the stability of the proposed stellar objects is investigated by the causality condition,Herrera cracking approach,and adiabatic index.Our findings indicate that the proposed stellar objects are viable as well as stable in the presence of correction terms. 展开更多
