低频阿尔文波对尘埃粒子的加速

Acceleration of dust particles by low-frequency Alfvén waves

V. Prudskikh, Yu. A. Shchekinov

摘要:

在非线性近似下研究了低频阿尔文波对带电尘埃粒子的加速效率。结果表明,尘埃粒子的纵向加速度与孤子振幅的平方成正比$O(|b_m|^2)$,而横向加速度与孤子振幅的平方成正比$O(|b_m|)$ .在星际介质的条件下,尘埃粒子的最终速度可以达到0.3至1 km/s $^{-1}$。

英文摘要:

We investigate the efficiency of acceleration of charged dust particles by low-frequency Alfvén waves in nonlinear approximation. We show that the longitudinal acceleration of dust particles is proportional to the square of the soliton amplitude $O(|b_m|^2)$, while the transversal acceleration is of $O(|b_m|)$. In the conditions of the interstellar medium the resulting velocity of dust particles can reach 0.3 to 1 km s$^{-1}$.
