چکیده
Abstract We study the excitation of fluting perturbations in a magnetic tube by an initially imposed kink mode. use ideal magnetohydrodynamic (MHD) equations cold-plasma approximation. also thin-tube approximation and scale dependent independent variables accordingly. Then we assume that dimensionless amplitude mode is small it as expansion parameter regular perturbation method. obtain expression for boundary second-order This superposition sausage perturbations.

Kink and fluting modes of stratified coronal magnetic loops with elliptical cross-sections
Aims. We study kink and fluting oscillations of a straight magnetic tube with an elliptic cross-section and density varying along the tube. Methods. The governing equations for kink and fluting modes in the thin tube approximation are derived. We found that there are two kink modes, polarised along the semimajor and semiminor axes of the elliptic cross-section. We have shown that the ratio of f...
متن کاملThe effects of twisted magnetic field on coronal loops oscillations and dissipation
The standing MHD modes in a zero-β cylindrical magnetic flux tube modelled as a straight core surrounded by a magnetically twisted annulus, both embedded in a straight ambient external field is considered. The dispersion relation for the fast MHD waves is derived and solved numerically to obtain the frequencies of both the kink (m = 1), and fluting (m = 2, 3) waves. Damping rates due to both vi...

متن کاملMechanism of edge localized mode mitigation by resonant magnetic perturbations.
A possible mechanism of edge localized modes (ELMs) mitigation by resonant magnetic perturbations (RMPs) is proposed based on the results of nonlinear resistive magnetohydrodynamic modeling using the jorek code, realistic JET-like plasma parameters and an RMP spectrum of JET error-field correction coils (EFCC) with a main toroidal number n=2 were used in the simulations. Without RMPs, a large E...
متن کاملStanding kink oscillations of thin twisted magnetic tubes with continuous equilibrium magnetic field
In this article we study standing kink waves in twisted magnetic tubes. We use the cold plasma and thin tube approximation. We assume that the plasma density is constant inside and outside the tube. We also assume that the magnetic twist is weak and take the ratio of the azimuthal and axial component of the magnetic field to be of the order of ratio of the tube radius and tube length. The azimu...
