论文摘要
本文探讨了Kerr-Newman-Kasuya Black Hole周围的Ergoregion，Horizons和Cightular Geodesics的特征。我们研究了自旋和敌对电荷参数对所述黑洞的奇异，事件范围和静态极限表面的影响。我们观察到，电气以及磁电荷参数都会降低事件范围和静态极限的半径，同时增加了Ergoregion的面积。将获得的结果与从Kerr和Schwarzschild黑洞获得的结果进行了比较。此外，我们找出了圆形空物测量学的光子轨道，并研究了粒子内粒子的角速度。
This article explores the characteristics of ergoregion, horizons and circular geodesics around a Kerr-Newman-Kasuya black hole. We investigate the effect of spin and dyonic charge parameters on ergoregion, event horizon and static limit surface of the said black hole. We observed that both electric, as well as magnetic charge parameters, results in decreasing the radii of event horizon and static limit, whereas increasing the area of ergoregion. The obtained results are compared with that acquired from Kerr and Schwarzschild black holes. Moreover, we figured out the photons orbit of circular null geodesics and studied the angular velocity of a particle within ergoregion.
