在瓦兹无视界黑洞上

On the Vaz no horizon black hole

Hristu Culetu

摘要:

我们提出了一个无视界的黑洞,它的坍缩物质在事件视界附近和形成之前凝聚。与Vaz的模型[arXiv:1407.3823]相比,我们的内部几何只取决于一个参数$r_{0}$ -量子涨落显著的区域的半径。当内部流体的状态方程为$p_{r} = -ρ$且横向压力为零时,表面应力张量对应于具有负表面张力的各向异性流体。利用坍缩恒星边界上的结条件,我们发现$r_{0}$是它的史瓦西半径的一半,而不是$2M$,就像瓦斯以前得到的尘埃球。

英文摘要:

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 $r_{0}$ - the radius of the region where quantum fluctuations are significant. While the equation of state of the inner fluid is $p_{r} = -ρ$ 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 $r_{0}$ is half its Schwarzschild radius and not $2M$, as previously obtained by Vaz for a dust ball.
