Discovery of the Earth's Van Allen radiation belts by instruments flown on Explorer 1 in 1958
was the first major discovery of the Space Age. The observation of distinct inner and outer …

The past decade transformed our observational understanding of energetic particle
processes in near‐Earth space. An unprecedented suite of observational systems was in …

One of the most important issues in space physics is to identify the dominant processes that
transfer energy from the solar wind to energetic particle populations in Earth's inner …

To achieve a better understanding of the dominant loss mechanisms for the rapid dropouts
of radiation belt electrons, three distinct radiation belt dropout events observed by Van Allen …

The year 2019 marks the 60th anniversary of the concept of radial diffusion in
magnetospheric research. This makes it one of the oldest research topics in radiation belt …

Dipolarization front (DF)—a sharp boundary with scale of ion inertial length (c/ωpi) in the
Earth's magnetotail—can also have fine structures at electron scale (c/ωpe). Such electron …

Many spacecraft fly within or through a natural and variable particle accelerator powered by
the coupling between the magnetosphere and the solar wind: the Earth's radiation belts …

Abstract Ultra‐low‐frequency (ULF) waves are known to radially diffuse hundreds‐keV to
few‐MeV electrons in the magnetosphere, as the range of drift frequencies of such electrons …

The rolling‐pin distribution of suprathermal electrons (40–200 keV), showing electron pitch
angles primarily at 0°, 90°, and 180°, has recently been reported behind dipolarization fronts …

We present dynamic simulations of energy‐dependent losses in the radiation belt “slot
region” and the formation of the two‐belt structure for the quiet days after the 1 March storm …
