Abstract

We propose a no horizon black hole whose collapsing matter condenses close to the event horizon and before its formation. Compared to Vaz's model [arXiv: 1407.3823], our interior geometry depends only on one parameter r0r_{0} - the radius of the region where quantum fluctuations are significant. While the equation of state of the inner fluid is pr=ρp_{r} = -\rho and the traverse pressures are vanishing, the surface stress tensor corresponds to an anisotropic fluid with negative surface tension. Using the junction conditions on the boundary of the collapsing star, we found that r0r_{0} is half its Schwarzschild radius and not 2M2M, as previously obtained by Vaz for a dust ball.
