Role of Minimal Geometric Deformation in Constructing Stellar Models in f ( Q , L m ) Theory: Stability Analysis under Kohler-Chao-Tikekar Spacetime

This research examines a static self-gravitating spherical spacetime and derives two anisotropic solutions using the gravitational decoupling technique in f(Q, L m ) gravity affected by an electromagnetic field. By changing the radial metric potential, we get two different sets of modified field equations. The first configuration represents the isotropic fluid distribution, and hence, we use the Kohler-Chao-Tikekar solution to address it. On the other hand, the second sector encompasses the impact of the additional source. To solve this system, we impose certain limits such as mimicking density and pressure. Furthermore, we investigate the impact of charge and the decoupling parameter on resulting physical quantities graphically. We also analyze some other physical attributes of both solutions, including mass, compactness, redshift, energy conditions, and stability. Ultimately, both of our solutions demonstrate stable geometries for certain parametric values within the considered gravitational framework.
