Solar Wind Dependence on Source Distance from the Open-Closed Boundary
Chloe P. Wilkins, David I. Pontin, Anthony R. Yeates +2
The origin and variability of the slow solar wind remains an open question in solar physics, but is thought to be closely linked to dynamics at the Sun's open-closed magnetic flux…
The Effects of Energy Conservation in Simulating Solar Eruptions
Xianyu Liu, Spiro K. Antiochos, Nishtha Sachdeva +6
Strict energy conservation is, perhaps, the most basic principle in all physics, but has proven to be difficult to satisfy in numerical simulations of solar eruptions. The Alfvén…
Effects of the Background Magnetic Field on Flux Rope Eruptions
Xianyu Liu, Spiro K. Antiochos, Igor V. Sokolov +5
Solar eruptive events are generally believed to involve magnetic flux ropes (MFR), formed either in the pre-eruptive phase of the event or during the eruption itself. These MFR eru…
Dynamics of Streamers and Pseudostreamers and Implications for the Solar Wind
Sahel Dey, David I. Pontin, Spiro K. Antiochos
The origin of the Sun's slow wind and its inherent variability remain unknown, but there is increasing evidence that interactions between closed and open magnetic flux in the coron…
Determining the 3D Dynamics of Solar Flare Magnetic Reconnection
Joel T. Dahlin, Spiro K. Antiochos, Peter F. Wyper +2
Solar flares are major space weather events that result from the explosive conversion of stored magnetic energy into bulk motion, plasma heating, and particle acceleration. While t…
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…
