A comparison study of a solar active-region eruptive filament and a neighboring non-eruptive filament [PDF]

open access: yesResearch in Astronomy and Astrophysics, 2016
Solar active region (AR) 11283 is a very magnetically complex region and it has produced many eruptions. However, there exists a non-eruptive filament in the plage region just next to an eruptive one in the AR, which gives us an opportunity to perform a comparison analysis of these two filaments. The coronal magnetic field extrapolated using a CESE-MHD-

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 FILAMENT MATERIAL OSCILLATIONS AND DRAINAGE BEFORE ERUPTION [PDF]

open access: yesThe Astrophysical Journal, 2014
Both large-amplitude longitudinal (LAL) oscillations and material drainage in a solar filament are associated with the flow of material along the filament axis, often followed by an eruption. However, the relationship between these two motions and a subsequent eruption event is poorly understood.

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.

Mini-filaments – small-scale analogues of solar eruptive events? [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
AbstractMini-filaments are a small-scale phenomenon of the solar chromosphere, which frequently occur across the entire disk (see e.g. Wang, Li, Denker, et al. 2000). They share a variety of characteristics with their larger-scale cousins and may serve as a proxy for more complex systems. They play an important role in the energy and mass supply to the

Prediction of Solar Eruptions Using Filament Metadata

open access: yesThe 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 ...

Causal Relationships between Eruptive Prominences and Coronal Mass Ejections [PDF]

open access: yes, 2007
A close association between eruptive prominences and CMEs, both slow and fast CMEs, was reported in many studies. Sometimes it is possible to follow the material motion starting from the prominence (filament) activation to the CME in the high corona ...

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.
