Compact stars in $f(R,T)$ gravity

TL;DR

This paper develops analytical models of compact stars within $f(R,T)$ gravity, considering conformal motion and a linear equation of state, and compares the models with observational data of known compact stars.

Contribution

It introduces new solutions for compact stars in $f(R,T)$ gravity with conformal symmetry and analyzes their physical viability against observational constraints.

Findings

Models describe radiating compact stars consistent with observations

Analytical solutions satisfy physical acceptability criteria

Exploration of $f(R,T)$ gravity effects on star structure

Abstract

In the present paper we generate a set of solutions describing the interior of a compact star under $f(R,T)$ theory of gravity which admits conformal motion. We consider the equation of state (EOS) $p=\omega\rho$ with $0<\omega<1$ for the fluid distribution consisting normal matter, $\omega$ being the EOS parameter. We therefore explore several aspects of the model analytically along with graphical representations to check the physical validity as well as acceptability of it within specified observational constraint in connection to a dozen of the compact star candidates. It is shown from the presented model that these objects are nothing but radiating compact stars.
