Frontiers in Astronomy and Space Sciences, 2023 Solar coronal jets are frequently occurring collimated ejections of solar plasma, originating from magnetically mixed polarity locations on the Sun of size scale comparable to that of a supergranule.

ERUPTION OF A SOLAR FILAMENT CONSISTING OF TWO THREADS
The Astrophysical Journal, 2012 The trigger and driving mechanism for the eruption of a filament consisting of two dark threads was studied with unprecedented high cadence and resolution of He II 304 angstrom observations made by the Atmospheric Imagining Assembly (AIA) on board the Solar Dynamics Observatory (SDO) and the observations made by the Solar Magnetic Activity Research ...

Filament eruptions and the impulsive phase of solar flares
The Astrophysical Journal, 1988 Filament motion during the onset of the solar flare impulsive phase is examined. The impulsive phase onset is established from profiles of about 30 keV X-ray fluxes and the rapid flare brightenings characteristic of the H-alpha flash phase. The filament motion begins several minutes before the impulsive or flash phase of the flare.

Small-scale motions in solar filaments as the precursors of eruptions [PDF]
Publications of the Astronomical Society of Japan, 2019 Abstract Filaments, the dense cooler plasma floating in the solar corona supported by magnetic fields, generally exhibit certain activations before they erupt. In our previous study (Seki et al. 2017, ApJ, 843, L24), we observed that the standard deviation of the line-of-sight (LOS) velocities of the small-scale motions in a filament ...

Onset mechanism of solar eruptions [PDF]
, 2018 Solar eruptions are the most energetic phenomena observed in the solar system observed as flares, coronal mass ejections (CMEs) and filament/prominence eruption.

Hinode Observations of the Onset Stage of a Solar Filament Eruption [PDF]
Publications of the Astronomical Society of Japan, 2007 Abstract We used Hinode X-Ray Telescope (XRT) and Solar Optical Telescope (SOT) filtergraph (FG) Stokes-V magnetogram observations, to study the early onset of a solar eruption that includes an erupting filament that we observe in TRACE EUV images.

Plasma Brightenings in a Failed Solar Filament Eruption
The Astrophysical Journal, 2017 Abstract Failed filament eruptions are solar eruptions that are not associated with coronal mass ejections. In a failed filament eruption, the filament materials usually show some ascending and falling motions as well as generating bright EUV emissions.

SOLAR FILAMENT MATERIAL OSCILLATIONS AND DRAINAGE BEFORE ERUPTION [PDF]
The Astrophysical Journal, 2014 Both large-amplitude longitudinal (LAL) oscillations and material drainage in a solar filament are associated with the flow of material along the filament axis, often followed by an eruption. However, the relationship between these two motions and a subsequent eruption event is poorly understood.

The Astrophysical Journal, 2022 Abstract Both observations and simulations suggest that the solar filament eruption is closely related to magnetic flux emergence. It is thought that the eruption is triggered by magnetic reconnection between the filament and the emerging flux. However, the details of such a reconnection are rarely presented. In this study, we report the
