Structure, stability, and evolution of magnetic flux ropes from the perspective of magnetic twist
We investigate the evolution of NOAA Active Region (AR) 11817 during 2013 August 10–12,
when it developed a complex field configuration and produced four confined, followed by …

Magnetic flux ropes in the solar corona: structure and evolution toward eruption
R Liu - Research in Astronomy and Astrophysics, 2020 - iopscience.iop.org
Magnetic flux ropes are characterized by coherently twisted magnetic field lines, which are
ubiquitous in magnetized plasmas. As the core structure of various eruptive phenomena in …

Ideal MHD instabilities for coronal mass ejections: interacting current channels and particle acceleration
We review and discuss insights on ideal magnetohydrodynamic (MHD) instabilities that can
play a role in destabilizing solar coronal flux rope structures. For single flux ropes, failed or …

Unambiguous evidence of filament splitting-induced partial eruptions
Coronal mass ejections are often considered to result from the full eruption of a magnetic
flux rope (MFR). However, it is recognized that, in some events, the MFR may release only …

Formation and eruption of a double-decker filament triggered by micro-bursts and recurrent jets in the filament channel
We present the observations of a double-decker filament to study its formation, triggering,
and eruption physics. It is observed that the double-decker filament was formed by splitting …

Observation of a large-scale filament eruption initiated by two small-scale erupting filaments pushing out from below
Y Song, J Su, Q Zhang, M Zhang, Y Deng, X Bai, S Liu… - Solar Physics, 2024 - Springer
Filament eruptions often result in flares and coronal mass ejections (CMEs). Most studies
attribute the filament eruptions to their instabilities or magnetic reconnection. In this study …
