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 ...

On rotation of solar filaments [PDF]
Proceedings of the International Astronomical Union, 2006 The study of the differential rotation law is an important issue in solar physics. Earlier studies of filaments found formulae for their differential rotation at stable existence stage. This paper relies on Big Bear Solar Observatory H-alpha filtergrams to estimate angular velocities of quiescent filaments at different stages of existence.

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.

Latitude migration of solar filaments [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 The Carte Synoptique catalogue of solar filaments from March 1919 to December 1989, corresponding to complete cycles 16 to 21 is utilized to show latitudinal migration of filaments at low latitudes (less than 50 deg), and the latitudinal drift of solar filaments in each hemisphere in each cycle of the time interval is compared with the corresponding ...
