Abstract
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.
Highlights
General relativity (GR) is considered as the most fruitful theory for understanding the evolution of universe and its hidden secrets, yet the evidence of dark matter (DM) and the cosmic accelerating nature of spacetime put some challenges on this [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]
The first modification to GR gives birth to f (R) gravity, which provides a good attention while the extension of this modification gives rise to f (R, T ) gravity and attain much attentions because of some quantum effects arising in the theory
These modifications appear in the field of low energy action for effective quantum gravity theory
Summary
General relativity (GR) is considered as the most fruitful theory for understanding the evolution of universe and its hidden secrets, yet the evidence of dark matter (DM) and the cosmic accelerating nature of spacetime put some challenges on this [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]. Das et al [72] calculated exact relativistic models of spherical interiors in MGT and discussed the physical implications of their results on compact stars Yousaf and his collaborators examined the role of various curvature invariant functions on the existence as well as stability of the planar [74,75,76], spherical [17,77,78,79,80] and cylindrical [23,81,82,83] geometries. To explore the formation of relativistic anisotropic compact stellar objects in f (R, T ) gravity, we use two such a viable f (R, T ) models for three candidates of strange stars, i,e., Her X-1, SAXJ1808.4-3658 and 4U182030.
