Singularity formation in radiating star with dark energy background
Abstract
In this paper, we considered the gravitational collapse of a symmetric radiating star consisting of perfect fluid (baryonic) in the background of dark energy (DE) with general equation of state. The effect of DE on the singularity formation has been discussed first separately (only DE present) and then combination of both baryonic and DE interaction. We have also showed that DE components play important role in the formation of Black-Hole(BH). In some cases the collapse of radiating star leads to black hole formation and in other cases it forms Naked-Singularity(or, eternally collapse). The present work is in itself remarkable to describe the effect of dark energy on singularity formation in radiating star.

Last section concluded as- From above table-1 we see that due to the presence of $p_{DE}$, the loss of luminosity increases the when $\rho_0 > \frac{3R_0^2}{kr_{\sum}^2}$ and it slow down for $\rho_0 < \frac{3R_0^2}{kr_{\sum}^2}$. Thus for different value of $\epsilon^{'}$, $p_{DE}$ plays the important role in the formation of black hole
