通过 Penrose 过程从带电 Vaidya 黑洞提取能量

Extraction Energy From Charged Vaidya Black Hole Via Penrose Process

Vitalii Vertogradov

AI总结:

本文研究带电 Vaidya 时空中的 Penrose 过程,通过分析广义能层边界及负能量粒子轨道,指出该能层是暂时的且粒子无闭合轨道,并证明无法从黑洞高效提取大量能量。

摘要:

本文考虑了带电 Vaidya 时空中 Penrose 过程的类比。我们计算了广义能层的边界,在该能层中可能存在具有负能量的带电粒子,并证明其是暂时的。我们证明了广义能层内的负能量粒子不存在闭合轨道。我们研究了 Penrose 过程的效率问题,并表明无法从黑洞中提取大量能量。

英文摘要:

In this paper, we consider the analogy of the Penrose process in Charged Vaidya spacetime. We calculate the border of the generalized ergosphere, in which the charged particles with negative energy might exist, and show that it is temporary. We show that there are no closed orbits for particles with negative energy inside the generalized ergosphere. We investigate the question about the efficiency of the Penrose process and show that one can't extract large energies from a black hole.
