论文摘要
我们提出了一种新的解决方案，描述了低能杂音弦理论中四维旋转的常规带电黑洞。目前的解决方案的特征是其质量，带电和角动量。讨论了一些方面，包括事件范围，梯形和角速度。表明，稍后，我们对事件范围和Ergosphere的表达无法分析获得。另一方面，为了确保我们的解决方案是否描述了非旋转电荷的黑洞，我们使用两种类型的标量不变。收缩Ricci Tensor和Kretschmann标量。根据我们的结果，包括电荷不会改变黑洞的规律性。我们还提出了一种自然处方，以使带电的黑洞溶液最少违反弱能量条件。
We present a novel solution describing four dimensional rotating regular charged black hole in the low energy heterotic string theory. This present solution is characterized by its mass, charged, as well as angular momentum. Some aspect including event horizon, ergosphere, and the angular velocity are discussed. It is shown that later, our expression for event horizon and ergosphere cannot be obtained analytically. On the other hand, to ensure whether our solution describe a nonsingular rotating charged black hole, we use two type of scalar invariant; contracted Ricci tensor and Kretschmann scalar. From our result, the inclusion of charge does not alter the regularity of a black hole. We also proposed a natural prescription to have rotating charged black hole solution with a minimal violation of weak energy conditions.
