Realistic solutions of fluid spheres in [formula omitted] Gravity under Karmarkar condition

Abstract

This manuscript investigates the compact stars solutions in the background of observational data (radii and mass) by employing the Karmarkar condition under the f(G,T) modified gravity for an anisotropic source of fluid. For this study, we have assumed a specific model for grr metric potential function, which has fulfilled the Karmarkar condition. This assuming model helps to calculate another metric function gtt by using the Karmarkar condition scenario. Further, this study deals to discuss the necessary physically properties by using the observational data for 4U1538-52, LMCX-4, and PSRJ1614-2230 models with three different values of parameter β. It is depicted from this current study; the calculated solutions are physically acceptable with best degree of accuracy. All the physically necessary relevant parameters and properties compact stars are presented graphically. It is noticed during this study the parameter β, has some importance and considerable role for these calculated solutions. In the end, it is concluded that our obtained solutions are physically arguable with well-behaved nature for f(G,T) modified gravity for these discussed compact stars.
