AI总结:

研究通过带电流体与暗能量相互作用,提出非奇异内部解,匹配Reissner-Nordström-de Sitter外部几何,并探讨极端配置下的熵模型扩展。

摘要:

本文探讨了非相对论带电完美流体与暗能量相互作用下的引力坍缩。给定简单的能量传输因子,获得非奇异内部解,自然匹配Reissner-Nordström-de Sitter外部几何。我们还表明相互作用参数与最终形成黑洞的总电荷成正比。对于准极端配置,我们提出了一种扩展Bekenstein几何熵的熵模型,通过与极端黑洞面积成比例的附加常数进行扩展。

英文摘要:

In this essay we examine the gravitational collapse of a nonrelativistic charged perfect fluid interacting with a dark energy component. Given a simple factor for the energy transfer, we obtain a nonsingular interior solution which naturally matches the Reissner-Nordström-de Sitter exterior geometry. We also show that the interacting parameter is proportional to the overall charge of the final black hole thus formed. For the case of quasi-extremal configurations, we propose a statistical model for the entropy of the collapsed matter. This entropy extends Bekenstein's geometrical entropy by an additive constant proportional to the area of the extremal black hole.
