Falling Threads during Solar Filament Eruptions
The Astrophysical JournalMass drainage is frequently observed in solar filaments. During filament eruptions, falling material most likely flows along magnetic field lines, which may provide important clues for the magnetic structures of filaments.

Two-step solar filament eruptions [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 Coronal mass ejections (CMEs) are closely related to eruptive filaments and usually are the continuation of the same eruptive process into the upper corona.

Mini-filament Eruptions Triggering Confined Solar Flares Observed by ONSET and SDO [PDF]
Astrophysical Journal Letters, 2018 Using the observations from the Optical and Near-infrared Solar Eruption Tracer (ONSET) and the Solar Dynamics Observatory (SDO), we study an M5.7 flare in AR 11476 on 2012 May 10 and a micro-flare in the quiet Sun on 2017 March 23.

Sympathetic Quiet and Active Region Filament Eruptions [PDF]
Solar Physics, 2022 We present the observations of three sympathetic filament eruptions occurring on 19 July 2015, namely F1, F2, and F3. The events were observed in UV and EUV by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory and in Hα ...

Solar Filament Eruptions as Precursors to Flare–CME Events: Establishing the Temporal Connection
Astrophysical Journal, 2019 Elongated structures on the Sun’s surface known as filaments are known to have a connection with energetic events of space weather consequence (flares and coronal mass ejections (CMEs)).

Mechanism of the Failed Eruption of an Intermediate Solar Filament
The Astrophysical Journal, 2022 Solar filament eruptions can generate coronal mass ejections (CMEs), which are huge threats to space weather. Thus, we need to understand their underlying mechanisms.

Observational Evidence of the Kink Instability in Solar Filament Eruptions and Sigmoids [PDF]
Astrophysical Journal, 2005 Two lines of observational evidence are used to infer that the MHD helical kink instability is associated with solar eruptions. The senses of twist and writhe are determined in images of seven erupting filaments obtained at 10830, 1600, 195, and 171 ?. In every case the sense of twist is the same as the sense of writhe, as required for a kink.

Data-constrained Magnetohydrodynamic Simulation of an Intermediate Solar Filament Eruption [PDF]
The Astrophysical Journal, 2023 Solar eruptive activities could occur in weak magnetic field environments and over large spatial scales, which are especially relevant to eruptions involving intermediate or quiescent solar filaments.

Solar Flares Triggered by a Filament Peeling Process Revealed by High-resolution GST Hα Observations
The Astrophysical Journal LettersThe dynamic structures of solar filaments prior to solar flares provide important physical clues about the onset of solar eruptions. Observations of those structures under subarcsecond resolution with high cadence are rare.

Solar filament eruptions and their physical role in triggering Coronal Mass Ejections [PDF]
Advances in Space Research, 2012 Solar filament eruptions play a crucial role in triggering coronal mass ejections (CMEs). More than 80% of eruptions lead to a CME. This correlation has been studied extensively during the past solar cycles and the last long solar minimum. The statistics
