The Langmuir–Landau-Centrifugal Drive (LLCD), which can effectively “convert” gravitational energy into particles, is explored as a driving mechanism responsible for the extreme thermal luminosity acquired by some active galactic nuclei (AGN). For this purpose, we consider equations governing the process of heating of AGN magnetospheres. In particular, we examine the Fourier components of the momentum equation, the continuity equation and the Poisson equation in the linear approximation and estimate the growth rate of the centrifugally excited electrostatic waves and the increment of the Langmuir collapse. It is shown that the process of energy pumping is composed of three stages: in the first stage the energy is efficiently transferred from rotation to the electrostatic modes. In due course of time, the second regime-the Langmuir collapse-occurs, when energy pumping is even more efficient. This process is terminated by the Landau damping, when enormous energy is released in the form of heat. We show that the magnetospheres of the supermassive black holes with luminosities of the order of ${10}^{45-46}$ erg/s can be heated up to ${10}^{6-10}$ K.

关于AGN磁层的加热

Langmuir-Landau-Centrifugal Drive（LLCD）可以有效地将引力能量“转化”为粒子，它是一种驱动机制，可驱动某些活跃的银河系原子核（AGN）获得极高的光度。为此，我们考虑了控制AGN磁层加热过程的方程式。特别是，我们在线性近似中检查了动量方程，连续性方程和泊松方程的傅立叶分量，并估计了离心激发的静电波的增长率和朗缪尔坍塌的增量。结果表明，能量泵送过程由三个阶段组成：在第一阶段，能量被有效地从旋转模式转移到静电模式。在适当的时候，第二种政权-朗缪尔（Langmuir）崩溃发生了，能量泵的效率更高。当以热量的形式释放出巨大的能量时，该过程会被Landau阻尼终止。我们表明，超大质量黑洞的磁层的发光度约为${10}^{45-46}$ erg / s可以加热到 ${10}^{6-10}$ K.
