The Solar Energetic Particle Event on 2013 April 11: An Investigation of its Solar Origin and Longitudinal Spread
D. Lario, N. E. Raouafi, R. -Y. Kwon +4
We investigate the solar phenomena associated with the origin of the solar energetic particle (SEP) event observed on 2013 April 11 by a number of spacecraft distributed in the inn…
Diagnostics of Coronal Magnetic Fields Through the Hanle Effect in UV and IR Lines
N. E. Raouafi, P. Riley, S. Gibson +2
The plasma thermodynamics in the solar upper atmosphere, particularly in the corona, are dominated by the magnetic field, which controls the flow and dissipation of energy. The rel…
Heliophysics Discovery Tools for the 21st Century: Data Science and Machine Learning Structures and Recommendations for 2020-2050
R. M. McGranaghan, B. Thompson, E. Camporeale +14
Three main points: 1. Data Science (DS) will be increasingly important to heliophysics; 2. Methods of heliophysics science discovery will continually evolve, requiring the use of l…
Comparative Study of MHD Modeling of the Background Solar Wind
C. Gressl, A. M. Veronig, M. Temmer +4
Knowledge about the background solar wind plays a crucial role in the framework of space weather forecasting. In-situ measurements of the background solar wind are only available f…
Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum
N. E. Raouafi, L. Matteini, J. Squire +54
Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to determine the…
Extracting the Heliographic Coordinates of Coronal Rays using Images from WISPR/Parker Solar Probe
P. C. Liewer, J. Qiu, F. Ark +5
The Wide-field Imager for Solar Probe (WISPR) onboard Parker Solar Probe (PSP), observing in white light, has a fixed angular field of view, extending from 13.5 degree to 108 degre…
