Role of f(G,T) gravity on the evolution of relativistic stars
Abstract
The aim of this paper is to explore some physically viable aspects for the possible emergence of compact stars in f(G,T) theory of gravity with some particular models, where G and T are Gauss–Bonnet invariant and trace of stress–energy tensor, respectively. We present basic formalism of this modified theory in the presence of anisotropic source. We explore some realistic aspects using the energy conditions with physical parameters. Three distinct known star models namely, SAXJ1808.4−3658,Her X−1 and 4U1820−30, are used for this systematic investigation. The physical behavior of anisotropic stresses, energy density, energy conditions, measure of anisotropy and stability of compact stars are discussed through plots. We conclude that compactness at the core of a star model increases and energy conditions hold.
