Breakout/Interchange Reconnection as a driver of Jets, Fast CME, and Solar Energetic Particles
Pankaj Kumar, Judith T. Karpen, David Lario +4
Understanding how energetic particles are accelerated and released from the low corona into the interplanetary medium during solar eruptions is crucial for space weather research.…
System Size Dependence of Collisionless Reconnection Rate
Yi-Min Huang, Naoki Bessho, Li-Jen Chen +2
It is a widely accepted paradigm that collisionless magnetic reconnection proceeds at a universal fast rate of when normalized to a properly defined reconnecting magnetic…
Solar Eruption Onset and Particle Acceleration in Nested-Null Topologies
Pankaj Kumar, Judith T. Karpen, Peter F. Wyper +3
The magnetic breakout model explains a variety of solar eruptions, ranging from small-scale jets to large-scale coronal mass ejections (CMEs). Most of our previous studies are focu…
Imaging and Radio Signatures of Shock-Plasmoid Interaction
Pankaj Kumar, Judith T. Karpen, P. K. Manoharan +1
Understanding how shocks interact with coronal structures is crucial for understanding the mechanisms of particle acceleration in the solar corona and inner heliosphere. Using simu…
Observations of a New Form of Partial Filament Eruption
Abril Sahade, Judith Karpen, Spiro Antiochos
Coronal mass ejections (CMEs) and coronal jets are two of the best-studied forms of solar eruptions, with the same underlying physics. Previous studies have presented partial erupt…
X-ray/Radio Quasi-periodic Pulsations Associated with Plasmoids in Solar Flare Current Sheets
Pankaj Kumar, Judith T. Karpen, Joel T. Dahlin
Plasmoids (or magnetic islands) are believed to play an important role in the onset of fast magnetic reconnection and particle acceleration during solar flares and eruptions. Direc…
