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.

Formation and large-scale patterns of filament channels and filaments [PDF]

open access: yes, 2014
2015ASSL..415..355MThe properties and large-scale patterns of filament channels and filaments are considered. Initially, the global formation locations of filament channels and filaments are discussed, along with their hemispheric pattern.

Quantification of the Writhe Number of the Evolution of Solar Filament Axes

open access: yesThe Astrophysical Journal, 2023
Solar filament eruptions often show complex and dramatic geometric deformation that is highly relevant to the underlying physical mechanism triggering the eruptions.

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

Solar flux emergence : a three-dimensional numerical study [PDF]

open access: yes, 2008
Flux is continually emerging on the Sun, making its way from the solar interior up into the atmosphere. Emergence occurs on small-scales in the quiet Sun where magnetic fragments emerge, interact and cancel and on large-scales in active regions where ...

Statistical Study of Confined Filament/Prominence Eruptions during Solar Cycle 23

open access: yes, 2023
International audienceFilament/prominence eruptions can have a significant impact on Earth's upper atmosphere and space environment, and are the primary drivers of what is now called space weather. To distinguish the different types of filament eruptions

Will subglacial rhyolite eruptions be explosive or intrusive? Some insights from analytical models. [PDF]

open access: yes, 2007
Simple analytical models of subglacial eruptions are presented, which simulate evolving subglacial cavities and volcanic edifices during rhyolitic eruptions beneath temperate glaciers.

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.

Future high-resolution and high-cadence observations for unraveling small-scale explosive solar features

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Solar coronal jets are frequently occurring collimated ejections of solar plasma, originating from magnetically mixed polarity locations on the Sun of size scale comparable to that of a supergranule.
