A study on the aromaticity and magnetic properties of N-confused porphyrins [PDF]

open access: yesRoyal Society Open Science, 2020
In this paper, topological resonance energy (TRE) methods were used to describe the global aromaticity of nitrogen confused porphyrin (NCP) isomers. The TRE results show that all NCP isomers exhibit lower aromaticity than the normal porphyrins, and their

Monitoring of magnetospheric parameters based on cosmic ray effects in August 2018

open access: yesSolar-Terrestrial Physics, 2023
Using data (uncorrected for the temperature effect) from the global network of neutron monitors (GNNM), along with data from the Yakutsk muon telescope complex and the muon hodoscope URAGAN (Moscow), we have applied a modified spectrographic global ...

Van Allen Probes Observations of Oxygen Ions at the Geospace Plume

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The geospace plume couples the ionosphere, plasmasphere, and magnetosphere from sub-auroral regions to the magnetopause, on polar field lines, and into the magnetotail.

Simulation of Dynamic Evolution of Ring Current Ion Flux by a Lunar Base Energetic Neutral Atom (ENA) Imaging

open access: yesAstronomy, 2023
The distribution of energetic ion flux in the ring current region, such as a meteorological cumulonimbus cloud, stores up the particle energy for a geomagnetic substorm.

Energetic Neutral Atom Imaging of the Earth’s Ring Current and Some Results from the Chinese Double Star Program

open access: yesMagnetochemistry, 2023
The ring current region in the Earth’s magnetosphere contains energetic charged particles, which are injected from the magnetotail, get trapped in the inner magnetosphere, and finally drift around the Earth.

Statistics of geomagnetic storms: Global simulations perspective

open access: yesFrontiers in Astronomy and Space Sciences, 2022
We present results of 131 geomagnetic storm simulations using the University of Michigan Space Weather Modeling Framework Geospace configuration. We compare the geomagnetic indices derived from the simulation with those observed, and use 2D cuts in the ...
