Schwarzschild几何对等温等离子体波色散的影响

Effects of Schwarzschild Geometry on Isothermal Plasma Wave Dispersion

M. Sharif, Umber Sheikh

摘要:

分析了史瓦西视界附近等温等离子体波的行为。我们考虑一个非旋转的背景与非磁化和磁化等离子体。建立了等离子体处于等温状态的Schwarzschild平面模拟时空的广义相对论磁流体动力学方程。通过引入简谐波,对方程的摄动形式进行了线性化和傅立叶分析。在每种情况下,这些方程的行列式导致一个复杂的色散关系,它给出了波数的复数值。这已被用来讨论波的性质和它们在地平线附近的特性。

英文摘要:

The behavior of isothermal plasma waves has been analyzed near the Schwarzschild horizon. We consider a non-rotating background with non-magnetized and magnetized plasmas. The general relativistic magnetohydrodynamical equations for the Schwarzschild planar analogue spacetime with an isothermal state of the plasma are formulated. The perturbed form of these equations is linearized and Fourier analyzed by introducing simple harmonic waves. The determinant of these equations in each case leads to a complex dispersion relation, which gives complex values of the wave number. This has been used to discuss the nature of the waves and their characteristics near the horizon.
