Irregular proton injection to high energies at interplanetary shocks
Domenico Trotta, Timothy S. Horbury, David Lario +8
How thermal particles are accelerated to suprathermal energies is an unsolved issue, crucial for many astrophysical systems. We report novel observations of irregular, dispersive e…
Energetic particle dynamics in a simplified model of a solar wind magnetic switchback
F. Malara, S. Perri, J. Giacalone +1
Context. Recent spacecraft observations in the inner heliosphere have revealed the presence of local Alfvenic reversals of the magnetic field, while the field magnitude remains alm…
Effects of Coronal Magnetic Field Configuration on Particle Acceleration and Release during the Ground Level Enhancement Events in Solar Cycle 24
Wenlong Liu, Xiangliang Kong, Fan Guo +6
Ground level enhancements (GLEs) are extreme solar energetic particle (SEP) events that are of particular importance in space weather. In solar cycle 24, two GLEs were recorded on…
Multi-point Assessment of the Kinematics of Shocks (MAKOS): A Heliophysics Mission Concept Study
Katherine A. Goodrich, Lynn B. Wilson, Steven Schwartz +6
Collisionless shocks are fundamental processes that are ubiquitous in space plasma physics throughout the Heliosphere and most astrophysical environments. Earth's bow shock and int…
Interpretation of flat energy spectra upstream of fast interplanetary shocks
Silvia Perri, Giuseppe Prete, Gaetano Zimbardo +6
Interplanetary shocks are large-scale heliospheric structures often caused by eruptive phenomena at the Sun, and represent one of the main sources of energetic particles. Several i…
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…
