Alfvénic Motions in a Stratified Open Flux Tube: Transition from Propagating to Locally Standing Motions and Implications for the Kelvin-Helmholtz Instability
Mingzhe Guo, Bo Li, Yuhang Gao +1
Standing transverse waves in closed coronal structures have been widely studied as a possible route to energy dissipation, with resonant absorption transferring kink wave energy to…
Three-dimensional kink modes in solar coronal slabs: group velocities and their implications for impulsively excited waves
Jing Liu, Bo Li, Mijie Shi +2
Little attention has been paid to group velocities of three-dimensional (3D) MHD waves in solar coronal seismology. This study aims to present a rather comprehensive examination on…
The Effect of Gravitational Stratification on Kink Oscillations in Curved Coronal Loops
Mingzhe Guo, Bo Li, Mijie Shi
Kink oscillation frequency is a key parameter for coronal seismology. It is still unclear how gravitational stratification affects the kink frequency in curved coronal loops. This…
Temporal evolution of axially standing kink motions in solar coronal slabs: An eigenfunction expansion approach
Yuhong Gao, Bo Li, Mijie Shi +2
We aim to provide more insights into the applicability to solar coronal seismology of the much-studied discrete leaky modes (DLMs) in classic analyses. Under linear ideal pressurel…
Horizontally and vertically polarized kink oscillations in curved solar coronal loops
Mingzhe Guo, Tom Van Doorsselaere, Bo Li +1
Kink oscillations are frequently observed in coronal loops. This work aims to numerically clarify the influence of loop curvature on horizontally and vertically polarized kink osci…
Damped kink motions in a system of two solar coronal tubes with elliptic cross-sections
Mijie Shi, Bo Li, Shaoxia Chen +2
This study is motivated by observations of coordinated transverse displacements in neighboring solar active region loops, addressing specifically how the behavior of kink motions i…
Horizontally Polarized Kink Oscillations Supported by Solar Coronal Loops in an Asymmetric Environment
Mijie Shi, Bo Li, Shengju Yuan
Kink oscillations are ubiquitously observed in solar coronal loops, their understanding being crucial in the contexts of coronal seismology and atmospheric heating. We study kink m…
