论文摘要
在本文中，检查了带电和未充电的测试颗粒在旋转非线电荷黑洞中的运动。它的渐近性可以是保姆或反de保姆，具体取决于非线性参数的值；因此，该BH可以呈现一个，两个或三个范围，第三个是在de Sitter案例中的宇宙学视野。分析角和径向测试粒子运动，并将其线性电磁对应物Kerr-Newman Black Hole（KN-BH）进行比较。 kn-bh产生了几种差异，即，赤道不对称是通过NLE场增强的，对于带电的颗粒，禁止进入其中一个极点。此外，出现了外部地平线附近的第二个圆形轨道。非线性电磁场的存在会增加弯曲的弯曲轨道，从而更接近地平线。
In this paper the motion of charged and uncharged test particles in the rotating nonlinearly charged black hole is examined. Its asymptotics can be de Sitter or anti-de Sitter, depending on the value of the nonlinear parameter; consequently this BH can present one, two or three horizons, the third one being the cosmological horizon in the de Sitter case. Angular and radial test particle motions are analyzed and compared with its linear electromagnetic counterpart, the Kerr-Newman black hole (KN-BH). Several differences arise with the KN-BH, namely, the equatorial asymmetry is enhanced by the NLE field and for charged particles the access to one of the poles is forbidden; besides, a second circular orbit in the neighborhood of the external horizon appears; the presence of the nonlinear electromagnetic field increses the curvature producing bounded orbits closer to the horizon.
