Impact of Magnetosphere Forcing and Model Resolution on Joule Heating Estimates in WACCM‐X During the 24 August 2005 Storm

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract We investigate the high‐latitude Joule heating in a recently developed high‐resolution configuration of the WACCM‐X whole‐atmosphere model coupled to the MAGE model. Model resolution and geomagnetic forcing effects during the severe (Kp>8) $(Kp > 8)$ geomagnetic storm on 24 August 2005 are analyzed, distinguishing storm peak and recovery ...

Heating of the low-latitude solar wind by dissipation of turbulent magnetic fluctuations [PDF]

open access: yes, 2001
We test a theory presented previously to account for the turbulent transport of magnetic fluctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for the injection of magnetic energy

Soft Proton Environment Modeling for SMILE Using XGBoost and Solar Cycle–Informed Synthetic Data Sets

open access: yesSpace Weather, Volume 24, Issue 7, July 2026.
Abstract Soft proton contamination presents a persistent threat to the performance of space‐based X‐ray observatories such as ESA's upcoming Solar‐wind Magnetosphere Ionosphere Link Explorer (SMILE). This study develops a machine‐learning framework for modeling soft proton fluxes in the 92.2–159.7 keV range, tailored to SMILE's elliptical, highly ...

Search for gravitational waves associated with the InterPlanetary Network short gamma ray bursts [PDF]

open access: yes, 2012
We outline the scientific motivation behind a search for gravitational waves associated with short gamma ray bursts detected by the InterPlanetary Network (IPN) during LIGO's fifth science run and Virgo's first science run.

The Radial Variation of Suprathermal Particles in Stream Interaction Regions: Comparisons between Solar Orbiter, ACE, and STEREO-A

open access: yesThe Astrophysical Journal
With the launch of Solar Orbiter, the intensity and composition of suprathermal particles have been sampled within the inner heliosphere at distances between ∼0.3 and 1 au.

Cosmic Dust Flux During the Quaternary: The Record of Large Scoriaceous and Unmelted Micrometeorites From the Transantarctic Mountains Collection

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract We estimate the cosmic dust flux to Earth through the study of rare micrometeorites that preserve part of their precursor features during atmospheric entry heating, namely unmelted and scoriaceous subtypes. Combining high‐precision mass balance measurements, X‐ray computed microtomography and scanning electron microscopy, we studied mass, size

Polar, Cluster and SuperDARN evidence for high latitude merging during southward IMF: temporal/spatial evolution [PDF]

open access: yes, 2003
Magnetic merging on the dayside magnetopause often occurs at high latitudes. Polar measured fluxes of accelerated ions and wave Poynting vectors while skimming the subsolar magnetopause.

Updating the Electrostatic Model for Dust Impact Detection with Antenna Instruments

open access: yesThe Astrophysical Journal
Antenna instruments deployed in space are known to be sensitive to dust impacts, and the detected signals can be used to characterize the dust populations within the solar system.

Global Effect of Long‐Lasting 07–12 October 2024 Geomagnetic Storms During the Transition From a Strong (G3) to a Severe (G4) on the Geomagnetic Field and Ionospheric Parameters Distribution

open access: yesSpace Weather, Volume 24, Issue 7, July 2026.
Abstract This study investigates the co‐evolution of geomagnetic field disturbances with ionospheric parameters and their characteristic latitudinal signatures by conducting a location and time‐dependent analysis of the 07–12 October 2024 events, to fill crucial gaps in understanding the coupled response of the magnetosphere‐ionosphere system. This has
