On the Fine Structure of Solar Filaments [PDF]
The Astrophysical Journal, 2006 High-resolution Hα images of solar filaments show a variety of dark fine-structure fibrils, most of them aligned with the magnetic field that is sheared with respect to the filament long axis. Here we demonstrate how such fibrils can be explained in terms of the magnetic field dips produced by realistic mass loading due to plasma condensation along the

SWAYING THREADS OF A SOLAR FILAMENT [PDF]
The Astrophysical Journal, 2009 From recent high resolution observations obtained with the Swedish 1 m Solar Telescope in La Palma, we detect swaying motions of individual filament threads in the plane of the sky. The oscillatory character of these motions are comparable with oscillatory Doppler signals obtained from corresponding filament threads.

SOLAR MAGNETIZED “TORNADOES:” RELATION TO FILAMENTS [PDF]
The Astrophysical Journal, 2012 Solar magnetized "tornadoes", a phenomenon discovered in the solar atmosphere, appear as tornado-like structures in the corona but root in the photosphere. Like other solar phenomena, solar tornadoes are a feature of magnetized plasma and therefore differ distinctly from terrestrial tornadoes. Here we report the first analysis of solar "tornadoes" {Two

Magnetic Twists of Solar Filaments [PDF]
The Astrophysical Journal, 2021 Abstract Solar filaments are cold and dense materials situated in magnetic dips, which show distinct radiation characteristics compared to the surrounding coronal plasma. They are associated with coronal sheared and twisted magnetic field lines.

Prediction of Space Weather Events using Solar Filaments and Sound waves as Precursors
, 2023 This dissertation is an effort in adding to existing methods of predictive capability for space weather events such as coronal mass ejections (CMEs) and solar flares and to predict if these events will cause a geo-magnetic storm well in advance.

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 ...

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

Development and application of a global magnetic field evolution model for the solar corona [PDF]
, 2009 Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Midterm periods of solar filaments [PDF]
Journal of Geophysical Research: Space Physics, 2014 Abstract On 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:
