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.

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.

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.

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 ...

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.

Sympathetic Eruption of Two Filaments and Associated Solar Coronal Jet
The Astrophysical JournalCombining 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.

SYMPATHETIC SOLAR FILAMENT ERUPTIONS [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT 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 in the eruption.

Characterization of the Micro-Morphology and Compositional Distribution of Chang'e-5 Lunar Soil Mineral Surfaces Using TOF-SIMS. [PDF]
Adv Sci (Weinh)Lunar soil samples from Chang'e 5 are characterized by high‐resolution time‐of‐flight secondary ion mass spectrometry, which revealed uncommon vesicle patterns that may not be observed via the conventional scanning electron microscope with energy dispersive X‐ray.

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