Perpendicular Diffusion of Solar Energetic Particles: Model Results and Implications for Electrons [PDF]
, 2017 The processes responsible for the effective longitudinal transport of solar energetic particles (SEPs) are still not completely understood. We address this issue by simulating SEP electron propagation using a spatially 2D transport model that includes ...

The “FIP Effect” and the Origins of Solar Energetic Particles and of the Solar Wind [PDF]
, 2018 We find that the element abundances in solar energetic particles (SEPs) and in the slow solar wind (SSW), relative to those in the photosphere, show different patterns as a function of the first ionization potential (FIP) of the elements.

An extremely energetic cosmic ray observed by a surface detector array [PDF]
Science, 2023 Cosmic rays are energetic charged particles from extraterrestrial sources, with the highest-energy events thought to come from extragalactic sources. Their arrival is infrequent, so detection requires instruments with large collecting areas. In this work,

Pitch Angle Distributions of Energetic Particles Near Callisto [PDF]
, 2023 The Galileo spacecraft performed close flybys of the moon Callisto between 1996 and 2001. We reanalyzed particle data of the energetic particles detector onboard Galileo and derived pitch angle distributions in the energy range of several keV to MeV ...

From the Sun’s south to the north pole – Ulysses COSPIN/LET composition measurements at solar maximum [PDF]
Annales Geophysicae, 2003 Based on elemental abundance ratios derived from the Ulysses COSPIN/LET measurements, we classified the energetic particle populations during and after the socalled Fast Latitude Scan – the time period during which the Ulysses spacecraft traveled

Connecting the Properties of Coronal Shock Waves with Those of Solar Energetic Particles
Astrophysical Journal, 2019 We develop and exploit a new catalog of coronal pressure waves modeled in 3D to study the potential role of these waves in accelerating solar energetic particles (SEPs) measured in situ.

3He-rich Solar Energetic Particles in Helical Jets on the Sun [PDF]
, 2017 Particle acceleration in stellar flares is ubiquitous in the universe; however, our Sun is the only astrophysical object where energetic particles and their source flares can both be observed.

Solar energetic particles and radio burst emission [PDF]
, 2017 We present a statistical study on the observed solar radio burst emission associated with the origin of in situ detected solar energetic particles. Several proton event catalogs in the period 1996–2016 are used.
