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 $…
Global MHD Simulations of the Time-Dependent Corona
Roberto Lionello, Cooper Downs, Emily I. Mason +5
We describe, test, and apply a technique to incorporate full-sun, surface flux evolution into an MHD model of the global solar corona. Requiring only maps of the evolving surface f…
Energetic Proton Propagation and Acceleration Simulated for the Bastille Day Event of July 14, 2000
Matthew A. Young, Nathan A. Schwadron, Matthew Gorby +9
This work presents results from simulations of the 14 July 2000 ("Bastille Day") solar proton event. We used the Energetic Particle Radiation Environment Model (EPREM) and the CORo…
Slip-Back Mapping as a Tracker of Topological Changes in Evolving Magnetic Configurations
R. Lionello, V. S. Titov, Z. Mikić +1
The topology of the coronal magnetic field produces a strong impact on the properties of the solar corona and presumably on the origin of the slow solar wind. To advance our unders…
GPU Acceleration of an Established Solar MHD Code using OpenACC
R. M. Caplan, J. A. Linker, Z. Mikić +3
GPU accelerators have had a notable impact on high-performance computing across many disciplines. They provide high performance with low cost/power, and therefore have become a pri…
Sun-to-Earth MHD Simulation of the 14 July 2000 "Bastille Day" Eruption
Tibor Török, Cooper Downs, Jon A. Linker +6
Solar eruptions are the main driver of space-weather disturbances at the Earth. Extreme events are of particular interest, not only because of the scientific challenges they pose,…
