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 ...

Observations and Magnetohydrodynamic Simulation of External Reconnection Resulting in a Failed Filament Eruption

The Astrophysical Journal
Failed filament eruptions have been reported previously; however, the responsible physical mechanisms remain debated. Using multiwavelength data from Solar Orbiter and Solar Dynamics Observatory, we analyze a failed filament eruption on 2024 March 19 ...

Simple Model for Temporal Variations of Hα Spectrum by an Eruptive Filament from a Superflare on a Solar-type Star

The Astrophysical Journal
Flares are intense explosions on the solar and stellar surfaces, and solar flares are sometimes accompanied by filament or prominence eruptions. Recently, a large filament eruption associated with a superflare on a solar-type star EK Dra was discovered ...

Observations of a Two-sided Loop Jet and Magnetic Reconnection Involving a Medium-scale Filament Eruption

The Astrophysical Journal
Although multiscale filament eruptions serve as significant triggers for various energetic release processes in the solar atmosphere, the underlying mechanisms remain elusive.

Initiation of Solar Eruptions: Recent Observations and Implications for Theories [PDF]

, 2006
Solar eruptions involve the violent disruption of a system of magnetic field. Just how the field is destabilized and explodes to produce flares and coronal mass ejections (CMEs) is still being debated in the solar community.

Study of the Orientation of Erupting Magnetic Flux Ropes in Coronal Mass Ejections from the Solar Corona to 1 au

The Astrophysical Journal
The southward component of the interplanetary magnetic field, often originating from solar coronal mass ejections (CMEs), plays a crucial role in driving geomagnetic storms. Accurate prediction of the flux rope orientation of CMEs as they arrive at Earth

Automated High-Precision Recognition of Solar Filaments Based on an Improved U²-Net

Universe
Solar 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 ...

Dynamics of An Erupting Filament and a Coronal Loop during Their Interaction

The Astrophysical Journal
Although interactions between filaments and other atmospheric structures are frequently observed, detailed studies on how these interactions affect the dynamics of the involved structures remain scarce.
