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…

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 Tale of Two Shocks
Robert F. Wimmer-Schweingruber, Domenico Trotta, Rungployphan Kieokaew +23
Energetic particles in interplanetary space are normally measured at time scales that are long compared to the ion gyroperiod. Such observations by necessity average out the microp…
Flat-top electron velocity distributions driven by wave-particle resonant interactions
Sofia Zanelli, Silvia Perri, Martina Condoluci +6
The role of kinetic electrons in the excitation and sustainment of ion-bulk electrostatic waves in collisionless plasmas is investigated, with a focus on the physical mechanisms re…
