How gas-dynamic flare models powered by Petschek reconnection differ from those with ad hoc energy sources
Dana Longcope, Jim Klimchuk
Aspects of solar flare dynamics, such as chromospheric evaporation and flare light-curves, have long been studied using one-dimensional models of plasma dynamics inside a static fl…
Three-Year Global Survey of Coronal Null Points from Potential-Field-Source-Surface (PFSS) Modeling and Solar Dynamics Observatory (SDO) Observations
Michael Freed, Dana Longcope, David McKenize
This article compiles and examines a comprehensive coronal magnetic-null-point survey created by potential-field-source-surface (PFSS) modeling and Solar Dynamics Observatory/Atmos…
Breakout and Tether-cutting Eruption Models Are Both Catastrophic (Sometimes)
D. W. Longcope, T. G. Forbes
We present a simplified analytic model of a quadrupolar magnetic field and flux rope to model coronal mass ejections. The model magnetic field is two-dimensional, force-free and ha…
Patchy Reconnection in a Y-Type Current Sheet
M. G. Linton, C. R. DeVore, D. W. Longcope
We study the evolution of the magnetic field in a Y-type current sheet subject to a brief, localized magnetic reconnection event. The reconnection produces up- and down-flowing rec…
