摘要

In this work, we present a model for the gravitational collapse of baryonic matter influenced by quintessence scalar fields in the context of general relativity. Specifically, we develop a dynamic model of a spherically symmetric, radiating, collapsing star in the presence of dark energy, modeled as a quintessence field with an inverse power-law potential. The analysis is carried out using junction conditions, thereby extending earlier investigations on collapsing radiating stars with dark energy components. Our findings reveal that the quintessence field significantly affects the collapsing star’s thermal behavior, indicating a substantial impact on its temperature evolution.
