Supra-arcade Downflows in an Extensive Fan Associated with a Giant Quiescent Solar Filament Eruption
The Astrophysical JournalWe investigate the aftermath of a giant quiescent solar filament eruption on 2023 December 24. One feature of the eruption is an extensive fan above the filament channel that is about 3 times as wide as similar structures that appear above active regions

The Eruptive Duality of a Filament on 2023 April 21
The Astrophysical JournalHere we study a filament eruption on 2023 April 21. The filament was composed of two segments, named S1 and S2. Initially, the brightening and bidirectionally plasmoid flows appeared inside S1, and then the west part of S1 (WS1) experienced rapid rising ...
