Evaluating Nudging Techniques in Implementing the Lower Atmosphere Variability Induced by Tides and Gravity Waves Into the TIEGCM

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract We implement a nudging module into the Thermosphere Ionosphere Electrodynamics General Circulation Model (TIEGCM) to identify effective techniques for incorporating global‐scale tides and medium‐scale gravity waves (GWs) that induce ionospheric variability.

Excitation of Storm‐Time Pc5 ULF Waves During the 22 July 2009 Storm: Comparison of GOES, Ground Observations, and GEMSIS Coupled Simulation

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Internally driven ULF waves are excited in the premidnight region during the magnetic storm on 22 July 2009. The excitation of ULF waves was investigated based on the Geospace Environment Modeling System for Integrated Studies (GEMSIS) magnetosphere‐ionosphere coupled model, GOES spacecrafts, and ground magnetometers.

The new Felsenkeller 5 MV underground accelerator

, 2018
The field of nuclear astrophysics is devoted to the study of the creation of the chemical elements. By nature, it is deeply intertwined with the physics of the Sun. The nuclear reactions of the proton-proton cycle of hydrogen burning, including the 3He({\

The Influence of Interior Structure and Thermal State on Impact Melt Generation Upon Large Impacts Onto Terrestrial Planets

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract We investigate the melt production of planetary impacts as a function of planet size (R/REarth $R/{R}_{\text{Earth}}$ = 0.1–1.5), impactor size (L $L$ = 1–1,000 km), and core size ratio (Rcore/R ${R}_{\text{core}}/R$ = 0.2–0.8) using a combination of parameterized convection models and fully dynamical 2D impact simulations.

Solar Wind‐Magnetosphere Coupling Under Interim Steady Conditions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Solar wind—magnetosphere coupling is an important driver of dynamics within the magnetosphere–ionosphere–thermosphere system, traditionally modeled using coupling functions. Most coupling functions assume the interaction is one‐directional, that the solar wind conditions determine the energy that is transferred into the magnetosphere.

Predictions for the Shape and Orientation of Earth's Foreshock Radiation Sources

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Radio emission produced in Earth's foreshock is due to the bow shock reflecting some electrons back upstream into the foreshock, where they produce Langmuir waves and radio emissions near the electron plasma frequency fp ${f}_{p}$ and near 2fp $2{f}_{p}$.

Imprints of Intense Geomagnetic Storm on Very Low Frequency (VLF) Radio Waves Over the Mediterranean Region

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract The study of solar and geomagnetic activity effects on the D‐region ionosphere (60–90 km altitude) using signals from very low frequency and low frequency (VLF, 3–30 kHz) transmitters has garnered considerable attention over the past decades. This research investigates the impacts of the geomagnetic storm (GMS) of 23–24 March 2023, utilizing ...

The formation of planetary disks and winds: an ultraviolet view

, 2008
Planetary systems are angular momentum reservoirs generated during star formation. This accretion process produces very powerful engines able to drive the optical jets and the molecular outflows.

Asymmetric Ionospheric Disturbances Observed by GNSS During the 2017 Typhoon Talim and Doksuri: Origin and Characteristics

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract The influence of typhoons on the ionosphere has been mentioned in many studies, while the relationship and coupling processes remain elusive. Here, we report findings on concentric ionospheric disturbance (CIDs) during typhoon Talim and Doksuri, using the total electron content (TEC) data derived from the Global Navigation Satellite System ...
