CHIRALITY AND MAGNETIC CONFIGURATIONS OF SOLAR FILAMENTS [PDF]
The Astrophysical Journal, 2017 ABSTRACT It has been revealed that the magnetic topology in the solar atmosphere displays hemispheric preference, i.e., helicity is mainly negative/positive in the northern/southern hemispheres, respectively. However, the strength of the hemispheric rule and its cyclic variation are controversial.

Automated High-Precision Recognition of Solar Filaments Based on an Improved U2-Net
UniverseSolar filaments are a significant solar activity phenomenon, typically observed in full-disk solar observations in the H-alpha band. They are closely associated with the magnetic fields of solar active regions, solar flare eruptions, and coronal mass ...

A Breakout Model for Solar Coronal Jets with Filaments [PDF]
The Astrophysical Journal, 2018 Abstract Recent observations have revealed that many solar coronal jets involve the eruption of miniature versions of large-scale filaments. Such “mini-filaments” are observed to form along the polarity inversion lines of strong, magnetically bipolar regions embedded in open (or distantly closing) unipolar field. During the generation of

The HeI abundance in Solar filaments [PDF]
Astronomy & Astrophysics, 2005 Three filaments observed with the CDS instrument on the SOHO satellite are analysed to determine the HeI/HI ratio. The HI and Hel bound-free absorptions are the major processes responsible for the lower intensity of transition region (TR) lines observed above filaments.

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.

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.

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.
