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…

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…
