Prediction of Solar Eruptions Using Filament Metadata
Astrophysical Journal, Supplement Series, 2018 Abstract We perform a statistical analysis of erupting and non-erupting solar filaments to determine the properties related to the eruption potential. In order to perform this study, we correlate filament eruptions documented in the Heliophysics Event Knowledgebase (HEK) with HEK filaments that have been grouped together using a ...

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.

Why Do Torus-unstable Solar Filaments Experience Failed Eruptions? [PDF]
The Astrophysical Journal Letters, 2019 Abstract We study the magnetic field and 3D configuration of 16 filament eruptions during 2010 July–2013 February in order to investigate the factors that control the success and/or failure of solar eruptions. All of these events, i.e., eruptions that failed to be ejected and become coronal mass ejections, have filament maximum heights ...

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 ...

Development and application of a global magnetic field evolution model for the solar corona [PDF]
, 2009 Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

European climate response to tropical volcanic eruptions over the last half millennium [PDF]
, 2007 We analyse the winter and summer climatic signal following 15 major tropical volcanic eruptions over the last half millennium based on multi-proxy reconstructions for Europe. During the first and second post-eruption years we find significant continental

Mechanism of the Failed Eruption of an Intermediate Solar Filament
The Astrophysical Journal, 2022 Abstract Solar filament eruptions can generate coronal mass ejections (CMEs), which are huge threats to space weather. Thus, we need to understand their underlying mechanisms. Although many authors have studied the mechanisms for several decades, we still do not fully understand in what conditions a filament can erupt to become a CME or ...

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-
