Solar energetic particle variations [PDF]

Advances in Space Research, 2004
The population of energetic particles in the heliosphere changes from solar maximum to solar minimum. The ultimate driver for those variations is the Sun. Solar variability is reflected in the dynamics of the large-scale structure of the heliosphere, the solar output of energetic particles and most definitively in the intensity, energy and composition ...

Cold dark matter and primordial superheavy particles [PDF]

, 2002
The hypothesis that cold dark matter consists of primordial superheavy particles, the decay of short lifetime component of which led to the observable mass of matter while long living component survived up to modern times manifesting its presence in high

Transport of Solar Energetic Particles [PDF]

International Astronomical Union Colloquium, 1994
AbstractNew developments in the understanding of the interplanetary transport of solar cosmic rays are reviewed. Based on carefully analyzed solar particle events observed on the Helios and ISEE 3 spacecraft, the relation of transport parameters to the structure of the interplanetary magnetic field is discussed.

Slow relaxation to equipartition in spring-chain systems [PDF]

, 2010
In this study, one-dimensional systems of masses connected by springs, i.e., spring-chain systems, are investigated numerically. The average kinetic energy of chain-end particles of these systems is larger than that of other particles, which is similar ...

Energetic Particle Signatures Above Saturn's Aurorae [PDF]

Journal of Geophysical Research: Space Physics, 2020
AbstractNear the end of its mission, NASA's Cassini spacecraft performed several low‐altitude passes across Saturn's auroral region. We present ultraviolet auroral imagery and various coincident particle and field measurements of two such passes, providing important information about the structure and dynamics of Saturn's auroral acceleration region ...

A Living Catalog of Parker Solar Probe IS⊙IS Energetic Particle Enhancements

The Astrophysical Journal Supplement Series, 2023
Energetic charged particles are pervasive throughout the heliosphere with contributions from solar energetic particle events, stream and corotating interaction regions, galactic cosmic rays, anomalous cosmic rays, and suprathermal ions.

Proton Acceleration in Low-β Magnetic Reconnection with Energetic Particle Feedback

The Astrophysical Journal
Magnetic reconnection regions in space and astrophysics are known as active particle acceleration sites. There is ample evidence showing that energetic particles can take a substantial amount of converted energy during magnetic reconnection.

Drift induced perpendicular transport of solar energetic particles [PDF]

, 2013
Drifts are known to play a role in galactic cosmic ray transport within the heliosphere and are a standard component of cosmic ray propagation models. However, the current paradigm of solar energetic particle (SEP) propagation holds the effects of drifts

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
