Wave‐Based Quantification of Ion Composition in the Earth's Magnetosphere‐Ionosphere‐Coupling Region

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Ion composition critically determines the basic kinetic characteristics of plasma and affects energy transmission of the magnetosphere. However, it exhibits significant variations with altitude, latitude, local time, longitude, and also with geomagnetic and solar activity.

Magnetic Tilt Effect on Externally Driven Electromagnetic Ion Cyclotron (EMIC) Waves

Geophysical Research Letters, 2023
We examine coupling of fluctuations in the solar wind with electromagnetic ion cyclotron (EMIC) waves in the magnetosphere using an advanced full‐wave simulation code, Petra‐M. Dipole tilt dramatically affects the coupling process. While very little wave

Exploring the Swimming and Water Safety Behaviour Among Indian and Vietnamese Adults in Australia

Health Promotion Journal of Australia, Volume 37, Issue 2, April 2026.
ABSTRACT Issue Addressed From 2011 to 2021, drowning caused over 2.5 million preventable deaths, with Asia carrying the highest burden of drowning deaths. India and Vietnam are among the top 10 birth countries of people who drown in Australia. This study aimed to understand how Asian adults living in Australia develop health literacy in relation to ...

Parker Solar Probe Observations of Proton Core‐Beam Distributions in Heliospheric Current Sheet Region: Quasilinear Instability Analysis Combined With Collisional Relaxation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Parker Solar Probe has been proven as instrumental for the observation of young solar wind. During the encounters E‐07 and E‐08, PSP recorded the core plus beaming protons crossing the heliospheric current Sheet region. When the observed PSP data is plotted in the temperature ratio versus parallel beta space, it is found that the occurrence ...

Simultaneous occurrence of four magnetospheric wave modes and the resultant combined scattering effect on radiation belt electrons

Earth and Planetary Physics, 2022
We report a representative concurrent event of four wave modes at L ≈ 5.0, including electrostatic electron cyclotron harmonic (ECH) waves, exohiss, magnetosonic (MS) waves, and electromagnetic ion cyclotron (EMIC) waves, based on the observations from ...
