Interactions between Filament Fibrils and a Network Field
The Astrophysical Journal, 2023 Filaments are common structures in the solar atmosphere, and usually interact with their surrounding magnetic fields. However, interactions between filaments and network fields are rare.

SYMPATHETIC SOLAR FILAMENT ERUPTIONS [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT The 2015 March 15 coronal mass ejection as one of the two that together drove the largest geomagnetic storm of solar cycle 24 so far was associated with sympathetic filament eruptions. We investigate the relations between the different filaments involved in the eruption.

Dynamics of Threads Wrapping a Filament's Leg Prior to the Eruption on 2021 October 28
The Astrophysical Journal, 2023 Although the magnetic field structures of solar filaments have been studied for several decades, the detailed evolution of the structure around a filament prior to its eruption is rarely observed. On 2021 October 28 in AR 12887, a major solar flare (X1.0

Midterm periods of solar filaments [PDF]
Journal of Geophysical Research: Space Physics, 2014 AbstractOn the basis of the Carte Synoptique catalogue of solar filaments from March 1919 to December 1989, we measure power spectra of detrended full‐disk (FSFNs, latitudinal bands: 0∘–90∘), low‐latitude (LSFNs, latitudinal bands: <50∘), and high‐latitude (HSFNs, latitudinal bands: ≥50∘) solar filament numbers by Maximum Entropy Method (MEM) and ...

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

Filaments and the Solar Dynamo [PDF]
International Astronomical Union Colloquium, 1998 AbstractFilaments are a global phenomenon and their formation, structure and dynamics are determined by magnetic fields. So they are an important signature of the solar magnetism. The central mechanism in traditional mean-field dynamo theory is the alpha effect and it is a major result of this theory that the presence of kinetic or magnetic helicities ...

Horizontal flow below solar filaments [PDF]
Astronomy & Astrophysics, 2018 Context. Observations of the internal fine structures of solar filaments indicate that the threads of filaments follow magnetic field lines. The magnetic field inside the filament has a strong axial component. Some models of magnetic fields suggest that the field structure in filaments could be caused by the horizontal plasma velocity field near both ...

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 ...

Striation and convection in penumbral filaments [PDF]
, 2010 Observations with the 1-m Swedish Solar Telescope of the flows seen in penumbral filaments are presented. Time sequences of bright filaments show overturning motions strikingly similar to those seen along the walls of small isolated structures in the ...
