非旋转黑洞事件视界周围等离子体的波动性质

M. Sharif, G. Mustafa

摘要:

本文研究了Schwarzschild黑洞事件视界附近等离子体的波动性质。采用傅立叶分析的3+1扰动GRMHD方程,在此基础上得到了非旋转、旋转非磁化和旋转磁化背景的复色散关系。得到了传播和衰减矢量随折射率的变化曲线,研究了介质在事件视界附近的色散特性。结果表明,从史瓦西磁层中不能获得任何信息。此外,压力使波的正常色散停止存在。

英文摘要:

We have studied the wave properties of the cold and isothermal plasma in the vicinity of the Schwarzschild black hole event horizon. The Fourier analyzed perturbed 3+1 GRMHD equations are taken on the basis of which the complex dispersion relations are obtained for non-rotating, rotating non-magnetized and rotating magnetized backgrounds. The propagation and attenuation vectors along with the refractive index are obtained (shown in graphs) to study the dispersive properties of the medium near the event horizon. The results show that no information can be obtained from the Schwarzschild magnetosphere. Further, the pressure ceases the existence of normal dispersion of waves.
