A statistical analysis of the Kappa-type energy spectrum distribution of radiation belt electrons observed by Van Allen Probes

open access: yesEarth and Planetary Physics
The energy spectrum of energetic electrons is a key factor representing the dynamic variations of Earth’s Van Allen radiation belts. Increased measurements have indicated that the commonly used Maxwellian and Kappa distributions are inadequate for ...

Large-scale episodic enhancements of relativistic electron intensities in Jupiter's radiation belt

open access: yesEarth and Planetary Physics, 2021
Previous studies indicate that, in the Jovian magnetosphere, the long-term trend of the radial profile of relativistic electron intensities is primarily shaped by slow radial diffusion. However, measurements by the Galileo spacecraft reveal the existence

Catching Wyckoff’s Phantom: The Peculiar Crystal Structure of Orthorhombic Cs[ICl2]

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Over 100 years after the first crystallographic elucidation, the still elusive orthorhombic modification of Cs[ICl2] could be isolated and structurally elucidated from the reaction of aqueous H[ICl4] with Cs2CO3. The [ICl2]− anion shows an unusually large bond length asymmetry, which shows characteristics of a Cl−∙∙∙I–Cl complex with an extremely ...

Intense chorus waves are the cause of flux-limiting in the heart of the outer radiation belt

open access: yesScientific Reports, 2022
Chorus waves play a key role in outer Van Allen electron belt dynamics through cyclotron resonance. Here, we use Van Allen Probes data to reveal a new and distinct population of intense chorus waves excited in the heart of the radiation belt during the ...

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

open access: yesIntegrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

The influence of solar wind variability on magnetospheric ULF wave power [PDF]

open access: yes, 2015
Magnetospheric ultra-low frequency (ULF) oscillations in the Pc 4–5 frequency range play an important role in the dynamics of Earth's radiation belts, both by enhancing the radial diffusion through incoherent interactions and through the coherent drift ...
