Coronal Mass Ejections Deflected by Newly Emerging Flux: A Combined Analytic and Numerical Study

The Astrophysical Journal
Newly emerging flux (NEF) has been widely studied as a trigger of solar filament eruptions, but its influence on the subsequent dynamics remains poorly explored.

Segmentation and Tracking of Eruptive Solar Phenomena With Convolutional Neural Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Solar eruptive events are complex phenomena, which most often include coronal mass ejections (CME), CME‐driven compressive and shock waves, flares, and filament eruptions. CMEs are large eruptions of magnetized plasma from the Sun's outer atmosphere or corona, that propagate outward into the interplanetary space.

The Origin, Early Evolution and Predictability of Solar Eruptions [PDF]

, 2018
Coronal mass ejections (CMEs) were discovered in the early 1970s when space-borne coronagraphs revealed that eruptions of plasma are ejected from the Sun.

Structure and Dynamics of Erupting Solar Prominences Using the Rolling Hough Transform: Toward a Feature-oriented Classification

The Astrophysical Journal
The classification of solar prominences has proven to be challenging, due to their diverse morphologies and dynamical behavior. Complexity is heightened when considering eruptive prominences, where the dynamics demand methods capable of capturing ...

Sigmoid Formation, Filament Destabilization, and Initiation of Weak Flare by Tether Cutting Reconnection

The Astrophysical Journal
We have studied a B-class solar flare and an associated filament eruption through multiwavelength observations. The flare is triggered at 16:24 UT on 2017 June 7 from Active Region(AR) 12661, and it maximizes at 16:54 UT.

Reconnection Nanojets in an Erupting Solar Filament with Unprecedented High Speeds

The Astrophysical Journal Letters
Abstract Solar nanojets are small-scale jets generated by component magnetic reconnection, characterized by collimated plasma motion perpendicular to the reconnecting magnetic field lines. As an indicator of nanoflare events, they are believed to play a significant role in coronal heating.

Successive filament eruptions within one solar breakout event [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractThe magnetic breakout model has been widely used to explain solar eruptive activities. Here, we apply it to explain successive filament eruptions occurred in a quadrupolar magnetic source region. Based on the high temporal and spatial resolution, multi-wavelengths observations taken by the Atmospheric Imaging Assembly (AIA) on board the Solar ...

Supra-arcade Downflows in an Extensive Fan Associated with a Giant Quiescent Solar Filament Eruption

The Astrophysical Journal
We investigate the aftermath of a giant quiescent solar filament eruption on 2023 December 24. One feature of the eruption is an extensive fan above the filament channel that is about 3 times as wide as similar structures that appear above active regions

Radio dimming associated with filament eruptions in the meter and decimeter wavebands

Filament eruptions are considered to be a common phenomenon on the Sun and other stars, yet they are rarely directly imaged in the meter and decimeter wavebands.

The Noneruptive Reconfiguration of a Quiescent Filament After a Nearby Active Region Emergence

The Astrophysical Journal
The unpredictability of solar filament eruptions presents major challenges for forecasting space weather, since such eruptions frequently drive coronal mass ejections that impact the heliosphere.
