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…

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…
