Variations in Finite Difference Potential Fields
Ronald M. Caplan, Cooper Downs, Jon A. Linker +1
The potential field (PF) solution of the solar corona is a vital modeling tool for a wide range of applications, including minimum energy estimates, coronal magnetic field modeling…
Predicting the Structure of the Solar Corona and Inner Heliosphere during Parker Solar Probe's First Perihelion Pass
Pete Riley, Cooper Downs, Jon A. Linker +3
NASA's Parker Solar Probe (Parker) spacecraft reached its first perihelion of 35.7 solar radii on November 5th, 2018. To aid in mission planning, and in anticipation of the unprece…
Ion Charge States in a Time-Dependent Wave-Turbulence-Driven Model of the Solar Wind
Roberto Lionello, Cooper Downs, Jon A. Linker +4
Ion fractional charge states, measured in situ in the heliosphere, depend on the properties of the plasma in the inner corona. As the ions travel outward in the solar wind and the…
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…
Global Non-Potential Magnetic Models of the Solar Corona During the March 2015 Eclipse
A. R. Yeates, T. Amari, I. Contopoulos +17
Seven different models are applied to the same problem of simulating the Sun's coronal magnetic field during the solar eclipse on 2015 March 20. All of the models are non-potential…
Identifying Observables that can Differentiate Between Impulsive and Footpoint Heating: Time Lags and Intensity Ratios
Amy R. Winebarger, Roberto Lionello, Cooper Downs +2
Observations of coronal loops have identified several common loop characteristics, including that loops appear to cool and have higher than expected densities. Two potential heatin…
