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

Why torus-unstable solar filaments experience failed eruption? [PDF]
The Astrophysical Journal Letters, 2019 To investigate the factors that control the success and/or failure of solar eruptions, we study the magnetic field and 3-Dimensional (3D) configuration of 16 filament eruptions during 2010 July - 2013 February.

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).

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.

Sympathetic Partial and Full Filament Eruptions Observed in One Solar Breakout Event [PDF]
The Astrophysical Journal, 2012 We report two sympathetic solar eruptions, including a partial and a full flux rope eruption in a quadrupolar magnetic region, where a large and a small filament resided above the middle and the east neutral lines respectively.

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.

Observations of a Failed Solar Filament Eruption Involving External Reconnection
The Astrophysical Journal, 2023 We report a failed solar filament eruption that involves external magnetic reconnection in a quadrupolar magnetic configuration. The evolution exhibits three phases of kinematic evolution: a slow rise, an acceleration, and a deceleration.

Partial Eruption of Solar Filaments. I. Configuration and Formation of Double-decker Filaments
The Astrophysical Journal, 2023 Partial eruptions of solar filaments are the typical representatives of solar eruptive behavior diversity. Here we investigate a typical filament partial eruption event and present integrated evidence for the configuration of the pre-eruption filament ...

Reconnection Nanojets in an Erupting Solar Filament with Unprecedented High Speeds
The Astrophysical Journal LettersSolar nanojets are small-scale jets generated by component magnetic reconnection, characterized by collimated plasma motion perpendicular to the reconnecting magnetic field lines.
