摘要：
The present paper is devoted to investigate the possible emergence of relativistic compact stellar objects through modified f (R, T) gravity. For anisotropic matter distribution, we used Krori and Barura solutions and two notable and viable f (R, T) gravity formulations. By choosing particular observational data, we determine the values of constant in solutions for three relativistic compact star candidates. We have presented some physical behavior of these relativistic compact stellar objects and some aspects like energy density, radial as well as transverse pressure, their evolution, stability, Eos parameters, measure of anisotropy and energy conditions.
