Three-dimensional Velocity Fields of the Solar Filament Eruptions Detected by CHASE

open access: yesThe Astrophysical Journal Letters
The eruption of solar filaments, also known as prominences appearing off limb, is a common phenomenon in the solar atmosphere. It ejects massive plasma and high-energy particles into interplanetary space, disturbing the solar-terrestrial environment.

Sympathetic Partial Filament Eruptions Caused by the Interaction between Two Nearby Filaments

open access: yesThe Astrophysical Journal, 2023
To better understand the physical connections in sympathetic solar eruptions, we investigated the interaction between two nearby filaments and their successive partial eruptions in the active region (AR) NOAA 12866 on 2021 September 9 by using data from ...

Observational Evidence of the Kink Instability in Solar Filament Eruptions and Sigmoids [PDF]

open access: yesAstrophysical 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.

Sympathetic Eruption of Two Filaments and Associated Solar Coronal Jet

open access: yesThe Astrophysical Journal
Combining the high-quality observations from the Solar Dynamics Observatory, the Global Oscillation Network Group, and the Chinese H α Solar Explorer, we report a solar coronal jet triggered by the sympathetic eruption of two filaments on 2024 January 11.

Pre-eruption Splitting of the Double-decker Structure in a Solar Filament [PDF]

open access: yesThe Astrophysical Journal, 2021
Abstract Solar filaments often erupt partially. Although how they split remains elusive, the splitting process has the potential of revealing the filament structure and eruption mechanism. Here we investigate the pre-eruption splitting of an apparently single filament and its subsequent partial eruption on 2012 September 27.

Heating of Quiescent Coronal Loops Caused by Nearby Eruptions Observed with the Solar Dynamics Observatory and the Solar Upper Transition Region Imager

open access: yesThe Astrophysical Journal, 2023
How structures, e.g., magnetic loops, in the upper atmosphere, i.e., the transition region and corona, are heated and sustained is one of the major unresolved issues in solar and stellar physics.

The role of filament activation in a solar eruption [PDF]

open access: yesAstronomy & Astrophysics, 2012
Observations show that the mutual relationship between filament eruptions and solar flares cannot be described in terms of an unique scenario. In some cases, the eruption of a filament appears to trigger a flare, while in others the observations are more consistent with magnetic reconnection that produces both the flare observational signatures (e.g ...

Observation of Two Splitting Processes in a Partial Filament Eruption on the Sun: The Role of Breakout Reconnection

open access: yesThe Astrophysical Journal, 2023
Partial filament eruptions have often been observed; however, the physical mechanisms that lead to filament splitting are not yet fully understood.

On the partial eruption of a bifurcated solar filament structure [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT The partial eruption of a filament channel with bifurcated substructures is investigated using data sets obtained from both ground-based and space-borne facilities. Small-scale flux reconnection/cancellation events in the region triggered the pile-up of ambient magnetic field, observed as bright extreme ultraviolet (EUV) loops ...
