Reformation of Supercritical Perpendicular Shock
Yuri V. Khotyaintsev, Domenico Trotta, Daniel B. Graham
Super-critical collisionless shocks are not static structures but evolve continuously as they reflect incoming ions back upstream. The physical process responsible for this non-sta…
Energetic particle-mediated interplanetary shocks observed by Solar Orbiter
D. Trotta, D. Lario, B. Reville +10
Context: In collisionless shocks, energetic particles can carry sufficient pressure to modify the upstream plasma and the shock structure itself, a regime often invoked in theories…
Energy Evolution from the Chromosphere to the Heliosphere in the 2021 October 28 Solar Eruption
Katharine K. Reeves, Daniel B. Seaton, Cynthia Cattell +20
We perform a detailed study of the energetics for a well-observed solar eruption and flare that occurred on 28 October 2021. This event included a GOES class X1.0 flare, a global E…
Compressive Structures in the Foreshock of Collisionless Shocks
Savvas Raptis, Domenico Trotta, Drew L. Turner +11
Collisionless shocks are fundamental accelerators of energetic particles; yet, the observations of nonlinear foreshock structures, which are essential in acceleration processes, di…
Velocity-space turbulent cascade in the near-Sun solar wind: first insights from the Parker Solar Probe mission
A. Larosa, O. Pezzi, T. Bowen +11
In space plasmas, the rarity of collisions leads to complex structures in the velocity space where a turbulent cascade of the velocity distribution function fluctuations is thought…
Ion-Scale Solitary Structures in the Solar Wind Observed by Solar Orbiter and Parker Solar Probe
Yufei Yang, Timothy S. Horbury, Domenico Trotta +12
We investigate a class of ion-scale magnetic solitary structures in the solar wind, characterized by distinct magnetic field enhancements and bipolar rotations over spatial scales…
