报告摘要：Inthis talk, we study the impact of three different f (R,T ) gravity models inthe modeling of anisotropic relativistic stellar structures, where R is theRicci scalar and T is the trace of the energy-momentum tensor. For thispurpose, we assume static geometry of spherically symmetric self-gravitatingobject and after choosing appropriate vacuum solution, we evaluated some constraintsfor the smooth matching of exterior and interior geometries at the boundarysurface. We considered observational values of three well-known stellarstructures and checked the viability of energy conditions in the presence ofquadratic, exponential and cubic f (R,T ) gravity models. The distributions ofenergy density, behavior of anisotropic pressure, role of fundamentalgravitational forces as well as stability investigation have been performedthrough plots in the realistic modeling of compact stars. We infer thatmodified gravitational theories could be treated as viable tool to study theexistence of compact stellar structures at both theoretical and cosmologicalscales.
