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.

Probable detection of an eruptive filament from a superflare on a solar-type star [PDF]

太陽型星のスーパーフレアから噴出する巨大フィラメントを初検出 --昔の、そして今の惑星環境や文明に与える脅威--. 京都大学プレスリリース. 2021-12-10.Solar flares are often accompanied by filament/prominence eruptions (~10⁴ K and ~10¹⁰⁻¹¹ cm⁻³), sometimes leading to coronal mass ejections that directly affect the Earth’s

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

Astronomy & 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 ...

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

Monthly 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 ...

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 ...

Two-step solar filament eruptions [PDF]

Monthly Notices of the Royal Astronomical Society, 2017
Coronal mass ejections (CMEs) are closely related to eruptive filaments and usually are the continuation of the same eruptive process into the upper corona. There are failed filament eruptions when a filament decelerates and stops at some greater height in the corona. Sometimes the filament after several hours starts to rise again and develops into the

A new paradigm for solar filament eruptions [PDF]

Journal of Geophysical Research: Space Physics, 2001
This article discusses the formation, magnetic structure, and eruption of solar filaments in terms of two contrasting paradigms. The standard paradigm is that filaments are formed by condensation of plasma on coronal magnetic fields that are twisted or dimpled as a result of photospheric motions.

Eruptive and Quasi-Eruptive Disappearing Solar Filaments and Their Relationship with Coronal Activities [PDF]

Publications of the Astronomical Society of Japan, 2003
Abstract By measuring the 3-D velocity fields of 35 disappearing filaments (Disparition Brusques: DBs) on the solar disk, we studied the causal relationship between the motions of $\mathrm{H}\alpha$ DBs and the associated coronal phenomena.
