强磁场中黑洞周围粒子辐射光的红移

Redshift of light emitted by particles orbiting a black hole immersed in a strong magnetic field

L. A. López, Nora Bretón

摘要:

在本文中,我们分析的频率移动的粒子发射的光描述稳定的圆形测地线周围的静态黑洞沉浸在外部磁场的任意强度。该系统由爱因斯坦-麦克斯韦方程组的恩斯特解表示。磁场的存在和它的大小会影响测地线和围绕黑洞运行的中性粒子或带电粒子发出的光的红蓝移。当关闭磁场时,我们恢复了围绕史瓦西黑洞运行的粒子的特征红移。

英文摘要:

In this paper we analyze the frequency shifts of the light emitted by particles describing stable circular geodesics around a static black hole immersed in an external magnetic field of arbitrary strength. This system is represented by the Ernst solution of the Einstein-Maxwell equations. The presence of the magnetic field and its magnitude affects both the geodesics and the red-blueshifts of the light emitted by neutral or charged particles orbiting the black hole. When the magnetic field is turned off we recover the characteristic redshifts coming from particles orbiting a Schwarzschild black hole.
