Abstract

We explore the implications of Rainbow Gravity on the properties of quark stars (QSs), hypothesized compact stars composed of strange quark matter. Utilizing the theories of Rainbow Gravity, this study integrates these frameworks to analyze QSs, particularly focusing on their structural and stability characteristics under extreme conditions. By employing the modified gravitational field equations and energy-dependent spacetime metrics, we investigate how these alterations affect the theoretical predictions concerning QSs, potentially providing insights into quantum chromodynamics at high energy scales. Our results indicate that within the Rainbow Gravity framework, QSs can potentially exceed the typical 2M<inf>⊙</inf> mass limit, suggesting a stiffer equation of state and larger radii compared to predictions by General Relativity. These findings highlight significant modifications in the structure and stability characteristics of QSs, offering new perspectives on the interplay between gravity and quantum field theory.
