Coronal mass ejections (CMEs) and eruptive flares (EFs) are the most energetic explosions in the solar system. Their underlying origin is the free energy that builds up slowly in the sheared magnetic field of a filament channel. We report the first end-to-end numerical simulation of a CME/EF, from zero-free-energy initial state through filament-channel formation to violent eruption, driven solely by the magnetic-helicity condensation process. Helicity is the topological measure of linkages…

From Pseudostreamer Jets to Coronal Mass Ejections: Observations of the Breakout Continuum
The magnetic breakout model, in which reconnection in the corona leads to destabilization of a filament channel, explains numerous features of eruptive solar events, from small-scale jets to
Modeling a Coronal Mass Ejection from an Extended Filament Channel. I. Eruption and Early Evolution
We present observations and modeling of the magnetic field configuration, morphology, and dynamics of a large-scale, high-latitude filament eruption observed by the Solar Dynamics Observatory. We
A Model for the Coupled Eruption of a Pseudostreamer and Helmet Streamer
A highly important aspect of solar activity is the coupling between eruptions and the surrounding coronal magnetic field topology, which determines the trajectory and morphology of the event and can
Escape of Flare-accelerated Particles in Solar Eruptive Events
Impulsive solar energetic particle events are widely believed to be due to the prompt escape into the interplanetary medium of flare-accelerated particles produced by solar eruptive events. According
Variability of the Reconnection Guide Field in Solar Flares
Solar flares may be the best-known examples of the explosive conversion of magnetic energy into bulk motion, plasma heating, and particle acceleration via magnetic reconnection. The energy source for
Particle Acceleration and Transport during 3D CME Eruptions
We calculate particle acceleration during CME eruptions using combined magnetohydrodynamic (MHD) and test-particle models. The CMEs are generated via the breakout mechanism and both 2D and 3D MHD
Heating and Eruption of a Solar Circular-ribbon Flare
We studied a circular-ribbon flare, SOL2014-12-17T04:51, with emphasis on its thermal evolution as determined by the Differential Emission Measure (DEM) inversion analysis of the extreme ultraviolet
Magnetic flux ropes in the solar corona: structure and evolution toward eruption
Magnetic flux ropes are characterized by coherently twisted magnetic field lines, which are ubiquitous in magnetized plasmas. As the core structure of various eruptive phenomena in the solar
The Dynamic Formation of Pseudostreamers
Streamers and pseudostreamers structure the corona at the largest scales, as seen in both eclipse and coronagraph white-light images. Their inverted-goblet appearance encloses broad coronal loops at
Eruption and Interplanetary Evolution of a Stealthy Streamer-Blowout CME Observed by PSP at ∼0.5 AU
Streamer-blowout coronal mass ejections (SBO-CMEs) are the dominant CME population during solar minimum. Although they are typically slow and lack clear low-coronal signatures, they can cause


The Mechanism for the Energy Buildup Driving Solar Eruptive Events
The underlying origin of solar eruptive events (SEEs), ranging from giant coronal mass ejections to small coronal-hole jets, is that the lowest-lying magnetic flux in the Sun's corona undergoes
Rotation of Coronal Mass Ejections during Eruption
Understanding the connection between coronal mass ejections (CMEs) and their interplanetary counterparts (ICMEs) is one of the most important problems in solar-terrestrial physics. We calculate the
A Model for Solar Coronal Mass Ejections
We propose a new model for the initiation of a solar coronal mass ejection (CME). The model agrees with two properties of CMEs and eruptive flares that have proved to be very difficult to explain
A universal model for solar eruptions.
Simulations of a coronal jet driven by filament ejection are reported, whereby a region of highly sheared magnetic field near the solar surface becomes unstable and erupts, and show that magnetic reconnection causes the energy release via 'magnetic breakout'-a positive-feedback mechanism between filament ejections and reconnection.

We have investigated the onset and acceleration of coronal mass ejections (CMEs) and eruptive flares. To isolate the eruption physics, our study uses the breakout model, which is insensitive to the

Vortex and sink flows in eruptive flares as a model for coronal implosions
Eruptive flares are sudden releases of magnetic energy that involve many phenomena, several of which can be explained by the standard 2D flare model and its realizations in three-dimensions. We
Filament Channel Formation via Magnetic Helicity Condensation
A major unexplained feature of the solar atmosphere is the accumulation of magnetic shear in the form of filament channels at photospheric polarity inversion lines (PILs). In addition to free energy,
