Effects of dark energy on compact stellar configurations in Rastall Teleparallel Gravity

This paper examines dark-energy compact stars under the paradigm of modified Rastall teleparallel gravity. This is the primary analysis of dark energy celestial phenomena under this modified gravitational theory. Utilizing the torsion-based functions, [Formula: see text] and [Formula: see text], we examined their impacts within a spherically symmetric space-time designated as the inner geometry, while employing the Schwarzschild geometry as the outside space-time. This study examines several features of dark energy in stars, encompassing dark energy pressure components, energy conditions, and equation of state components. Our findings indicate that the detected adverse behavior of certain stellar parameters provided substantial evidence, ensuring the presence of dark energy in celestial configurations. Thorough examinations of energy conditions, pressure profiles, sound speeds, adiabatic index, gradients, mass function, compactness, and redshift function provide a full evaluation, confirming the viability and authenticity of the analyzed stellar configuration.
