Miniature Filament Eruptions and their Reconnections in X-Ray Jets: Evidence for a New Paradigm [PDF]
, 2014 We investigate the onset of approximately10 random X-ray jets observed by Hinode/XRT. Each jet was near the limb in a polar coronal hole, and showed a ``bright point'' in an edge of the base of the jet, as is typical for previously-observed X-ray jets ...

Investigating an Erupting Metric-decimetric Radio Depression and Its Physical Origin
The Astrophysical JournalWe present direct metric-decimetric radio imaging observations of a fascinating quiescent filament eruption on 2024 March 17 using data from the DAocheng Radio Telescope, with a combination of the Solar Dynamics Observatory and the Chinese H α Solar ...

Rotation of a Solar Jet Driven by Plasma Flow along Helical Magnetic Fields in an Active Region
The Astrophysical JournalSolar jets, collimated plasma ejections driven by magnetic reconnection, play a vital role in energy transport and coronal heating. While rotational motions in jets are often attributed to magnetic field untwisting, alternative explanatory mechanisms ...

Observations and 3D Magnetohydrodynamic Modeling of a Confined Helical Jet Launched by a Filament Eruption [PDF]
, 2019 We present a detailed analysis of a confined filament eruption and jet associated with a C1.5 class solar flare. Multi-wavelength observations from the Global Oscillations Network Group and Solar Dynamics Observatory reveal the filament forming over ...

Multithermal Structure of Solar Jets Based on Combined EUV and Hα Observations
The Astrophysical JournalThis study investigates the multithermal structure of solar jets by combining extreme ultraviolet and H α observations, addressing whether cool and hot components originate from the same jet, their morphological similarities and differences, and the role

The Eruptive Duality of a Filament on 2023 April 21
The Astrophysical JournalHere we study a filament eruption on 2023 April 21. The filament was composed of two segments, named S1 and S2. Initially, the brightening and bidirectionally plasmoid flows appeared inside S1, and then the west part of S1 (WS1) experienced rapid rising ...
