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…

Origin of Unusual Composition of 3He-Rich Solar Energetic Particles

R. Bucik, G. M. Mason, S. M. Mulay +3

We examine 3He-rich solar energetic particles (SEPs) detected on 2023 October 24-25 by Solar Orbiter at 0.47 au. The measurements revealed that heavy-ion enhancements increase irre…

CoSEE-Cat: A Comprehensive Solar Energetic Electron event Catalogue obtained from combined in situ and remote-sensing observations from Solar Orbiter -- Catalogue description and first statistical results

A. Warmuth, F. Schuller, R. Gómez-Herrero +39

(abridged) The acceleration of particles at the Sun and their propagation through interplanetary space are key topics in heliophysics. Specifically, solar energetic electrons (SEEs…

Bidirectional anisotropic solar energetic particle events observed by Solar Orbiter

Zheyi Ding, Robert F. Wimmer-Schweingruber, Yu Chen +12

Solar Energetic Particle (SEP) events are critical for understanding particle acceleration and transport in the heliosphere. While most SEP events involve outward streaming particl…

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…

Investigation of Inverse Velocity Dispersion in a Solar Energetic Particle Event Observed by Solar Orbiter

Zheyi Ding, F. Robert Wimmer-Schweingruber, Alexander Kollhoff +15

Inverse velocity dispersion (IVD) events, characterized by higher-energy particles arriving later than lower-energy particles, challenge the classical understanding of SEP events a…

An Overview of Solar Orbiter Observations of Interplanetary Shocks in Solar Cycle 25

D. Trotta, A. Dimmock, H. Hietala +17

Interplanetary shocks are fundamental constituents of the heliosphere, where they form as a result of solar activity. We use previously unavailable measurements of interplanetary s…

Composition variation of the May 16 2023 Solar Energetic Particle Event observed by Solar Orbiter and Parker Solar Probe

Z. G. Xu, C. M. S Cohen, R. A. Leske +13

In this study, we employ the combined charged particle measurements from Integrated Science Investigation of the Sun (\ISOIS) onboard the Parker Solar Probe (PSP) and Energetic Par…

Radial Evolution of ICME-Associated Particle Acceleration Observed by Solar Orbiter and ACE

Malik H. Walker, Robert C. Allen, Gang Li +5

On 2022 March 10, a coronal mass ejection (CME) erupted from the Sun, resulting in Solar Orbiter observations at 0.45 au of both dispersive solar energetic particles arriving prior…
