Role of particle creation mechanism on the collapse of a massive star

In this presentation the collapse dynamics of a spherically symmetric massive star in the framework of non-equilibrium thermodynamic prescription through particle creation mechanism has been studied. For simplicity, we have assumed the thermodynamic system is chosen to be adiabatic so that the effective bulk viscous pressure is linearly related to the particle creation rate. Consequently the evolution of the collapsing star also depends on the choice of particle creation rate. By suitable choice of creation rate as a function of the Hubble parameter, we found that the end state of the collapse may be either a black hole (BH) or a naked singularity (NS).
