Horizontal flow below solar filaments
Astronomy and 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.

Differential rotation of short-lived solar filaments [PDF]
Solar Physics, 1977 We have measured the rotation rate of short-lived solar filaments as a function of their latitude. The resulting rotation curve appears to be somewhat flatter than the corresponding curve for long-lived ...

Proper Motion of Solar Filaments [PDF]
Astronomy & Astrophysics, 1999 Precise measurements of heliographic position of solar filaments were used for describing the proper motion of solar filaments on the time-scale of one day. Only the velocity values more accurate than 100 m s−1 were used for the study. The filaments have a tendency to make a shaking or waving of the external structure and also to make a general ...

Where Do Solar Filaments Form? [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractIn the present study, we consider where large, stable solar filaments form relative to underlying magnetic polarities. We find that 92% of all large stable filaments form in magnetic configurations involving the interaction of two or more bipoles. Only 7% form above the Polarity Inversion Line (PIL) of a single bipole. This indicates that a key

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.
