Gravitational collapse of interacting combination of dark matter and dark energy in the context of brane world regime

摘要

In the scenario of an optimal consideration that is, homogeneous and flat spacetime, we study the Black Hole (BH) formation from the gravitational collapse of a spherical symmetric clump of matter in the case of the specific Dark Matter (DM) model interacting with Dark Energy (DE) in the context of the brane world regime. This clump of matter constituted of DM, pi M and DE, pi. In the present model, we consider anisotropic pressure in the energy-momentum tensor with a polytropic equation of state (EoS), pr = k pi and pt = omega pi, (k 2 omega -1). Our results show that the gravitational collapse of an interacting combination of DM and DE leads to the formation of BH in the presence of brane tension. Recent work provides the generalization of isotropic pressure to an-isotropic pressure in the energy-momentum tensor for the specific interacting combination model of DM and DE in a brane world regime.
