On the onset delays of solar energetic electrons and protons: Evidence for a common accelerator
R. D. Strauss, N. Dresing, I. G. Richardson +2
The processes responsible for the acceleration of solar energetic particles (SEPs) are still not well understood, including whether SEP electrons and protons are accelerated by com…
The modulation of anomalous and galactic cosmic ray oxygen over successive solar cycle minima
R. D. Strauss, R. A. Leske, J. S. Rankin
Both the recent 2009 and 2020 solar minima were classified as unusually quiet and characterized with unusually high galactic cosmic ray (GCR) levels. However, unlike the trends fro…
The radial variation of the solar wind turbulence spectra near the kinetic break scale from Parker Solar Probe measurements
S. Lotz, A. E. Nel, R. T. Wicks +7
In this study we examine the radial dependence of the inertial and dissipation range indices, as well as the spectral break separating the inertial and dissipation range in power d…
Anomalous Cosmic Ray Oxygen Observations in to 0.1 au
Jamie S. Rankin, David J. McComas, Richard A. Leske +10
The Integrated Science Investigation of the Sun instrument suite onboard NASA's Parker Solar Probe mission continues to measure solar energetic particles and cosmic rays closer to…
On the shape of SEP electron spectra: The role of interplanetary transport
R. Du Toit Strauss, Nina Dresing, Alexander Kollhoff +1
We address the effect of particle scattering on the energy spectra of solar energetic electron events using i) an observational and ii) a modeling approach. i) We statistically stu…
Voyager 2 enters interstellar space
R. Du Toit Strauss
After 41 years of travel, the Voyager 2 spacecraft joins its twin in interstellar space. A suite of papers report Voyager 2's experience of its transition through the heliosheath a…
Perpendicular Diffusion of Solar Energetic Particles: Model Results and Implications for Electrons
R. D. Strauss, N. Dresing, N. E. Engelbrecht
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…
On Aspects Pertaining to the Perpendicular Diffusion of Solar Energetic Particles
R. D. Strauss, H. Fichtner
The multitude of recent multi-point spacecraft observations of solar energetic particle (SEP) events have made it possible to study the longitudinal distribution of SEPs in great d…
