Escape of Flare-accelerated Particles in Solar Eruptive Events
S. Masson, S. K. Antiochos, C. R. DeVore
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 eruptiv…
Numerical Simulation of Helical Jets at Active Region Peripheries
Peter F. Wyper, C. Richard DeVore, Spiro K. Antiochos
Coronal jets are observed above minority polarity intrusions throughout the solar corona. Some of the most energetic occur on the periphery of active regions where the magnetic fie…
First Detection of Plasmoids from Breakout Reconnection on the Sun
Pankaj Kumar, Judith T. Karpen, Spiro K. Antiochos +2
Transient collimated plasma ejections (jets) occur frequently throughout the solar corona, in active regions, quiet Sun, and coronal holes. Although magnetic reconnection is genera…
The Role of Magnetic Helicity in Coronal Heating
Kalman J. Knizhnik, Spiro K. Antiochos, James A. Klimchuk +1
One of the greatest challenges in solar physics is understanding the heating of the Sun's corona. Most theories for coronal heating postulate that free energy in the form of magnet…
Determining the Transport of Magnetic Helicity and Free Energy in the Sun's Atmosphere
Peter W. Schuck, Spiro K. Antiochos
The most important factors determining solar coronal activity are believed to be the availability of magnetic free energy and the constraint of magnetic helicity conservation. Dire…
A Model for Energy Buildup and Eruption Onset in Coronal Mass Ejections
Joel T. Dahlin, Spiro K. Antiochos, C. Richard DeVore
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 t…
