Small-scale Turbulent Motion of the Plasma in a Solar Filament as the Precursor of Eruption
Daikichi Seki, Kenichi Otsuji, Hiroaki Isobe +5
A filament, a dense cool plasma supported by the magnetic fields in the solar corona, often becomes unstable and erupts. It is empirically known that the filament often demonstrate…

On the ratios of \ion{Si}{4} lines (1394/1403) in an emerging flux region
Durgesh Tripathi, V. N. Nived, Hiroaki Isobe +1
The resonance lines of \ion{Si}{4} formed at 1394 and 1403 Å are the most critical for the diagnostics of the solar transition region in the observations of the Interface Region…

Small-scale motions in solar filaments as the precursors of eruptions
Daikichi Seki, Kenichi Otsuji, Hiroaki Isobe +3
Filaments, the dense cooler plasma floating in the solar corona supported by magnetic fields, generally exhibit certain activations before they erupt. In our previous study (Seki e…
