Open-source Flux Transport (OFT). I. HipFT -- High-performance Flux Transport
Ronald M. Caplan, Miko M. Stulajter, Jon A. Linker +6
Global solar photospheric magnetic maps play a critical role in solar and heliospheric physics research. Routine magnetograph measurements of the field occur only along the Sun-Ear…

Energetic Particles from Quasi-Separatrix Layers and Current Sheets at the Sun
Nathan A. Schwadron, Ronald M. Caplan, Jon A. Linker +2
Quasi-separatrix layers (QSLs) at the Sun are created from regions where channels of open magnetic flux have footpoints near regions of large-scale closed magnetic flux. These regi…

Magnetogram-matching Biot-Savart Law and Decomposition of Vector Magnetograms
V. S. Titov, C. Downs, T. Török +3
We generalize a magnetogram-matching Biot-Savart law (BSL) from planar to spherical geometry. For a given coronal current density , this law determines the magnetic field $…
