论文摘要
黑洞可以积累大量能量，负责高能的天体物理现象 最近，提出了磁场的快速磁重新连接（MR）作为提取能量的新方法，在本文中，我们在大黄蜂Kerr-sen BH中研究了这种现象。我们发现，电荷参数的存在强烈改变了简单的KERR案例，即使对于不太旋转的黑洞（$ a \ sim 0.7 $），这种提取机制也可能成为可能。我们还表明，在适当的情况下，与Blandford-Znajek机制相比，MR更有效。最终，我们将这些结果与未找到和增强对Kerr溶液的典型黑洞解决方案进行了比较。
Black holes can accumulate a large amount of energy, responsible for highly energetic astrophysical phenomena Recently, fast magnetic reconnection (MR) of the magnetic field was proposed as a new way to extract energy and in this paper, we investigate this phenomena in a bumblebee Kerr-Sen BH. We find that the presence of the charge parameter strongly changes the simple Kerr case, making this extraction mechanism possible even for not extremely rotating black holes ($a \sim 0.7$). We also show that, under appropriate circumstances, MR is more efficient compared to the Blandford-Znajek mechanism. We finally compare these results with quintessence black-hole solutions not finding and enhancement respect to Kerr solution.
