Simulating the photospheric to coronal plasma using magnetohydrodyanamic characteristics I: data-driven boundary conditions
Lucas A. Tarr, N. Dylan Kee, Mark G. Linton +2
We develop a general description of how information propagates through a magnetohydrodynamic (MHD) system based on the method of characteristics and use that to formulate numerical…

Disentangling the Entangled Linkages of Relative Magnetic Helicity
Peter W. Schuck, Mark G. Linton
Magnetic helicity, , measures magnetic linkages in a volume. The early theoretical development of helicity focused on magnetically closed systems in bounded by $\m…

Large Photospheric Doppler Shift in Solar Active Region 12673: I. Field-Aligned Flows
Jiayi Liu, Xudong Sun, Peter W. Schuck +3
Delta () sunspots sometimes host fast photospheric flows along the central magnetic polarity inversion line (PIL). Here we study the strong Doppler shift signature in the centra…
