SYMPATHETIC SOLAR FILAMENT ERUPTIONS [PDF]
Astrophysical Journal Letters, 2016 The 2015 March 15 coronal mass ejection as one of the two that together drove the largest geomagnetic storm of solar cycle 24 so far was associated with sympathetic filament eruptions. We investigate the relations between the different filaments involved

Solar Filament Eruptions in H α Doppler Velocity
The Astrophysical Journal, 2023 We use observations taken with a novel solar telescope spectroheliograph to investigate the association between the early filament rise and coronal mass ejections (CMEs).

Three-dimensional Velocity Fields of the Solar Filament Eruptions Detected by CHASE [PDF]
The Astrophysical Journal LettersThe 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
The 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 ...

A Statistical Study of Solar Filament Eruptions that Form High-speed Coronal Mass Ejections [PDF]
Astrophysical Journal, 2019 Coronal mass ejections (CMEs) play a decisive role in driving space weather, especially the fast ones (e.g., with speeds above 800 km s−1). Understanding the trigger mechanisms of fast CMEs can help us gain important information in forecasting them.

Sun-as-a-star Observations of Obscuration Dimmings Caused by Filament Eruptions [PDF]
The Astrophysical JournalFilament eruptions often lead to coronal mass ejections (CMEs) on the Sun and are one of the most energetic eruptive phenomena in the atmospheres of other late-type stars.

The Impulsive Acceleration of a Solar Filament Eruption Associated with a B-class Flare
The Astrophysical Journal, 2023 The eruption of magnetic flux ropes (MFRs), often taking filaments together, leads to coronal mass ejections (CMEs). Theoretical studies propose that both the resistive magnetic reconnection and the ideal instability of an MFR system can release magnetic-

How Reconnection-unfavored Magnetic Flux Emergence Suppresses Solar Filament Eruptions
The Astrophysical Journal LettersMagnetic flux emergence is traditionally considered to be a key trigger of solar filament eruptions, yet its role in suppressing filament eruptions remains less understood.

Minifilament Eruptions as the Last Straw to Break the Equilibrium of a Giant Solar Filament
The Astrophysical JournalFilament eruptions are magnetically driven violent explosions commonly observed on the Sun and late-type stars, sometimes leading to monster coronal mass ejections that directly affect the nearby planets’ environments.
