Detailed Analysis of Relativistic Confi guration of Bardeen Anisotropic Spheres inModi fied f(G) Gravity
The objective of present work is to deal with physical features of anisotropic compact objects within the framework of f(G) modified theory of gravity. For our present work, the Einstein- Maxwell equations defined under the impression of charge by utilizing the Krori-Barua metric i.e, λ(r) = Xr2 + Y and β(r) = Zr2, described by spherically symmetric space-time. To accomplish the desired objective, we calculate the undefined constrains utilized within the stellar debate by using the comparison method of interior and exterior spacetime while Bardeen geometry consider as an exterior. Further, to analyze the stellar configuration of Bardeen compact stars by assuming viable f(G) models including logarithmic corrected, we establish some expressions for examining the components of pressure and density, respectively. We address the energy conditions to verify our model’s viability for the various star candidates. Some other physical features, such as equilibrium condition, equation of state parameters, adiabatic index, stability analysis, mass function, surface Redshift and compactness factor, have been investigated. Conclusively, all the obtained results shows that the system under consideration is physically stable, free from singularity, and viable. Keywords: Bardeen compact stars, f(G) modified gravity, Krori-Barua potential.
