New mechanism of acceleration of particles by stellar black holes

Abstract

In this paper, we study the efficiency of particle acceleration in the magnetospheres of stellar mass black holes. For this purpose, we consider the linearized set of the Euler equation, continuity equation and Poisson equation, respectively. After introducing the varying relativistic centrifugal force, we show that the charge separation undergoes the parametric instability, leading to generation of centrifugally-excited Langmuir waves. It is shown that these waves, via the Langmuir collapse damp by means of the Landau damping, as a result, energy transfers to particles accelerating them to energies of the order of [Formula: see text] eV.
