Stable Configurations of Dark Energy Stars in f(R,L_m,T) Gravity
Abstract
In the context of f(R,Lm,T) gravity, two analytical solutions are proposed in this study, representing the structure of compact spherical objects whose behavior is dominated by dark energy fluid parameters. The extended field equations are derived using a static interior spacetime under the considered model which characterize a geometric structure including both dark energy and ordinary matter. The field equations are solved using the connections between dark energy with conventional matter, which are governed by different equations of state. This analysis further employs the Kohler-Chao-Tikekar and Durgapal-Fluoria spacetimes as two distinct ansatzes to close the system of field equations, resulting in two independent solutions. For both solutions, the constants are fixed by matching the interior and exterior spacetimes at the boundary using junction conditions. This study also assesses the proposed models using data from SAX J1808.4-3658, and explore the implications of varying the parametric values within the standard modified framework. The analysis concludes that both models fulfil the necessary physical conditions to ensure their candidacy for realistic stellar structures.
