Energetic Particle Acceleration and Transport: Interplanetary Coronal Mass Ejections and Shocks
Olga E. Malandraki, Christina M. S. Cohen, Joe Giacalone +16
Solar Energetic Particles from suprathermal (few keV) up to relativistic (few GeV) energies constitute an important contributor to the characterization of the space environment. Em…
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…
Observations of stable pickup He tori in a magnetic flux rope at 0.85 au
Chaoran Gu, Lars Berger, Verena Heidrich-Meisner +3
Interstellar pickup ions originate from the neutral interstellar medium, are ionized in the heliosphere, and picked up by the solar wind. They initially form a torus-shaped velocit…
Probing Solar Wind Structures with Solar Energetic Particle Observations from Solar Orbiter
Xiaohang Chen, Gang Li, Joe Giacalone +12
The propagation of solar energetic particles (SEPs) through the heliosphere is primarily guided by the interplanetary magnetic field (IMF) which is embedded in the solar wind plasm…
Solar energetic electron transport across the heliospheric current sheet - A statistical study
C. Han, R. F. Wimmer-Schweingruber, P. Kühl +7
Solar eruptive events such as flares and coronal mass ejection (CME)-driven shocks can release solar energetic particles (SEPs) into the heliosphere. The heliospheric current sheet…
Shock properties for solar energetic particle events with signatures of inverse velocity arrival
A. Kouloumvakos, D. Lario, G. M. Mason +20
We present a detailed investigation of the shock properties associated with solar energetic particle (SEP) events that exhibit a concave (``nose-like'') shape in their energy spect…
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…
Anomalous cosmic rays within the inner heliosphere: Observations of helium by the High Energy Telescope onboard Solar Orbiter
Zigong Xu, Robert F. Wimmer-Schweingruber, Lars Berger +11
Radial gradients of cosmic rays are key parameters for understanding the transport of particles in space. Solar Orbiter, launched on 2020 February 10, approaches the Sun approximat…
