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.

Successive Solar Flares and Coronal Mass Ejections on 2005 September 13 from Noaa Ar 10808

, 2009
We present a multiwavelength study of the 2005 September 13 eruption from NOAA 10808 that produced total four flares and two fast coronal mass ejections (CMEs) within 1.5 hours.

The Triggering Mechanism of coronal jets and CMEs: Flux Cancelation [PDF]

Recent investigations show that coronal jets are driven by the eruption of a small-scale filament (10,000 - 20,000 km long, called a minifilament) following magnetic flux cancelation at the neutral line underneath the minifilament. Minifilament eruptions

EUV and HXR Signatures of Electron Acceleration During the Failed Eruption of a Filament

, 2012
We search for EUV brightenings in TRACE 171 {\AA} images and HXR bursts observed during failed eruptions. We expect that if an eruption is confined due to interaction with overlying magnetic structures then we should observe effects connected with ...

Ensemble Model Using the Fokker–Planck Equation and Alfvénic Drift for Estimating Proton Flux in Solar Energetic Particle Events

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract Observations of solar energetic particles (SEPs) accelerated at collisionless shocks driven by coronal mass ejections (CMEs) highlight the importance of understanding proton transport in velocity space. In this study, we present an ensemble model based on the one‐dimensional Fokker–Planck equation to estimate proton flux from CME‐driven shocks

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 ...

Is flux rope a necessary condition for the progenitor of coronal mass ejections?

, 2015
A magnetic flux rope structure is believed to exist in most coronal mass ejections (CMEs). However, it has been long debated whether the flux rope exists before eruption or is formed during eruption via magnetic reconnection.

Risk Assessment of the Ground Magnetic Response to the March and April 2023 Geomagnetic Storms Using Geomagnetically Induced Currents Indices

Space Weather, Volume 23, Issue 4, April 2025.
Abstract We analyzed the solar origin and ground response during the severe geomagnetic storms (GSs) of 23–24 March (GS1) and 23–24 April 2023 (GS2) using Geomagnetically Induced Currents Indices (GIC indices) computed from geomagnetic field data. The GSs were initiated by erupting filaments and associated slow (fast) halo coronal mass ejections on 20 ...

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.
