In this work, we studied the gravitational collapse of a spherically symmetric radiating star consisting of perfect fluid (baryonic) in the background of dark energy (DE) with an equation of state $p_{\mathrm{\text{DE}}}=\omega {\rho }_{\mathrm{\text{DE}}}$. The effect of DE on the singularity formation has been discussed in two separate cases: first when only DE is present, and the other, with a combination of both baryonic and DE interaction. We have shown that DE component $p_{\mathrm{\text{DE}}}$ plays an important role in the formation of black hole (BH). In some cases, the collapse of radiating stars leads to BH formation, and in other cases, it forms naked-singularity (or, eternally collapse). This study is in itself a significant work to describe the effect of DE on singularity formation in radiating stars.

在这项工作中，我们研究了在暗能量（DE）背景下由完美流体（重子）组成的球对称辐射星的引力坍缩，并具有状态方程$p_{\mathrm{\text{德}}}=\omega {\rho }_{\mathrm{\text{德}}}$. DE 对奇点形成的影响已在两种不同的情况下进行了讨论：第一种是仅存在 DE，另一种是重子和 DE 相互作用的组合。我们已经证明了 DE 组件$p_{\mathrm{\text{德}}}$在黑洞（BH）的形成中起重要作用。在某些情况下，辐射恒星的坍缩会导致 BH 的形成，而在其他情况下，它会形成裸奇点（或永远坍缩）。这项研究本身就是描述 DE 对辐射恒星奇点形成影响的一项重要工作。
