Mechanism of the Failed Eruption of an Intermediate Solar Filament

open access: yesThe 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 ...

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

open access: yes, 2022
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

Initiation and Early Kinematic Evolution of Solar Eruptions [PDF]

open access: yes, 2020
We investigate the initiation and early evolution of 12 solar eruptions, including six active-region hot channel and six quiescent filament eruptions, which were well observed by the Solar Dynamics Observatory, as well as by the Solar Terrestrial ...

The Impulsive Acceleration of a Solar Filament Eruption Associated with a B-class Flare

open access: yesThe 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-

Triggering Mechanism and Material Transfer of a Failed Solar Filament Eruption [PDF]

open access: yesThe Astrophysical Journal, 2020
Abstract Solar filament eruptions are often associated with solar flares and coronal mass ejections, which have the greatest impact on space weather. However, the fine structures and the trigger mechanisms of solar filaments are still unclear.

Sleuthing Stellar Filament Eruptions Using He 1083 nm: A Solar Test [PDF]

open access: yes, 2023
Much effort has gone into detecting stellar CMEs due to their importance for stellar mass and angular momentum loss, and planetary habitability. But what of their stealthier (flare-free) cousins, the filament eruptions (FE)?

Two-step solar filament eruptions [PDF]

open access: yesMonthly 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]

open access: yesJournal 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]

open access: yesPublications 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.
