Magnetospheric response to solar wind forcing: ultra-low-frequency wave–particle interaction perspective [PDF]
Annales Geophysicae, 2022 Solar wind forcing, e.g., interplanetary shock and/or solar wind dynamic pressure pulses impacting Earth's magnetosphere, manifests many fundamental important space physics phenomena, including producing electromagnetic waves, plasma heating, and ...

Short term Variability of the Sun Earth System: An Overview of Progress Made during the CAWSES II Period [PDF]
, 2015 This paper presents an overview of results obtained during the CAWSES II period on the short term variability of the Sun and how it affects the near Earth space environment. CAWSES II was planned to examine the behavior of the solar terrestrial system as

Simulations of Electron Acceleration at Collisionless Shocks: The Effects of Surface Fluctuations [PDF]
, 2006 Energetic electrons are a common feature of interplanetary shocks and planetary bow shocks, and they are invoked as a key component of models of nonthermal radio emission, such as solar radio bursts.

The role of interplanetary scattering in western hemisphere large solar energetic particle events [PDF]
, 2006 Using high-sensitivity instruments on the ACE spacecraft, we have examined the intensities of O and Fe in 14 large solar energetic particle events whose parent activity was in the solar western hemisphere.

Frontiers in Astronomy and Space Sciences, 2021 Solar energetic particles (SEPs) are sporadically ejected from the Sun during flares and coronal mass ejections. They are of major astrophysical interest, because the proximity of the Sun allows for detailed multi-messenger studies.

The physics of space weather/solar-terrestrial physics (STP): what we know now and what the current and future challenges are [PDF]
Nonlinear Processes in Geophysics, 2020 Major geomagnetic storms are caused by unusually intense solar wind southward magnetic fields that impinge upon the Earth's magnetosphere (Dungey, 1961). How can we predict the occurrence of future interplanetary events?

The mixing of interplanetary magnetic field lines: A significant transport effect in studies of the energy spectra of impulsive flares [PDF]
, 2000 Using instrumentation on board the ACE spacecraft we describe short-time scale (~3 hour) variations observed in the arrival profiles of ~20 keV nucleon^(–1) to ~2 MeV nucleon^(–1) ions from impulsive solar flares. These variations occurred simultaneously

Transmission and Emission of Solar Energetic Particles in Semi-transparent Shocks. [PDF]
, 2014 While major solar energetic particle (SEP) events are associated with coronal mass ejection (CME)-driven shocks in solar wind, accurate SEP measurements reveal that more than one component of energetic ions exist in the beginning of the events.

Nonlinear Interaction of Low-frequency Alfvén Waves and Ions
The Astrophysical Journal, 2023 The interaction between Alfvén waves and particles is a critical phenomenon in space and laboratory plasmas, and it has been observed that low-frequency Alfvén waves can accelerate and heat ions through subharmonic resonant interactions.
