Abstract

Oscillations of coronal loops with electric currents from one base to another are studied. The energy of longitudinal currents can be a source of energy for loop flares (Alfvén and Carlqvist, 1967). A simplified model of a loop in the form of a composite cylindrical magnetic tube containing a shell with a potential azimuthal magnetic field is considered for the theoretical study of oscillations of loops with longitudinal currents. The dispersion features of the tube natural kink oscillations are considered based on numerical calculations.

纵向电流的冕环的扭结振荡

摘要

研究了电流从一个碱基到另一个碱基的冠状环的振荡。纵向电流的能量可以成为环状火炬的能量来源（Alfvén和Carlqvist，1967）。考虑到具有纵向电流的环路振荡的理论研究，可以考虑采用复合圆柱磁管形式的环路简化模型，该复合圆筒形电磁管包含具有潜在方位角磁场的壳体。基于数值计算，考虑了管自然扭结振荡的色散特征。
