The Equilibrium of Coronal Loops Near Separatrices
The Astrophysical Journal, 2023 We present numerical models from the field-aligned HYDrodynamics and RADiation code (HYDRAD) of a highly asymmetric closed coronal loop with near-singular expansion factor.

Earthward O+ Injections in the Plasma Sheet Boundary Layer During Geomagnetic Storms
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract During geomagnetic storms, energetic ions are injected from the Earth's magnetotail along the plasma sheet boundary layer (PSBL). Owing to its off‐equatorial inclined orbit, the Arase satellite is in a prime position to observe these injections in the PSBL on the nightside at the apogee.

Modelling chromospheric evaporation in response to coronal heating [PDF]
, 2018 This thesis presents a new computationally efficient method for modelling the response of the solar corona to the release of energy. During impulsive heating events, the coronal temperature increases which leads to a downward heat flux into the ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract The April 2023 geomagnetic storm significantly impacted the thermosphere‐ionosphere system, particularly over South America and midlatitude regions. This study analyzes ground‐based geomagnetic and ionospheric data, alongside Swarm satellite measurements, to investigate the physical mechanisms driven by intense solar wind energy input ...

Propagation Dynamics of Fast Electron Beam and Its Electron Cyclotron Maser Emission
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract Fast electron beams (FEBs) and coherent radio bursts both are very common plasma activity phenomena in the cosmos. The electron cyclotron maser (ECM) instability driven by FEBs trapped in magnetic fields can directly amplify radio wave radiations.

The Astrophysical Journal, 2023 Anomalous ion heating is frequently observed to accompany magnetic reconnection, yet there is little consensus on its origin. Instead of the usual velocity-space analysis, we use phase-space analysis to exhaustively explain how ions are nonthermally ...

Space Weather, Volume 24, Issue 10, October 2026.Abstract Enhanced small‐scale ionospheric irregularities during geomagnetic storms can disturb Global Navigation Satellite System (GNSS) carrier‐phase tracking and are associated with reduced stability of ambiguity‐fixed precise point positioning (PPP‐AR), but their impact on kinematic positioning remains insufficiently quantified.

Constraining Coronal Heating: Employing Bayesian Analysis Techniques to Improve the Determination of Solar Atmospheric Plasma Parameters [PDF]
, 2010 One way of revealing the nature of the coronal heating mechanism is by comparing simple theoretical one dimensional hydrostatic loop models with observations at the temperature and/or density structure along these features. The most well-known method for
