Using Parker Solar Probe observations during the first four perihelia to constrain global magnetohydrodynamic models

Pete Riley, Roberto Lionello, Ronald M. Caplan +4

Parker Solar Probe (PSP) is providing an unprecedented view of the Sun's corona as it progressively dips closer into the solar atmosphere with each solar encounter. Each set of obs…

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…

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…

Solar Sources of Interplanetary Magnetic Clouds Leading to Helicity Prediction

Roger K. Ulrich, Pete Riley, T. Tran

This study identifies the solar origins of magnetic clouds that are observed at 1 AU and predicts the helical handedness of these clouds from the solar surface magnetic fields. We…
