Eruption of a Million-Kelvin Warm Magnetic Flux Rope on the Sun

The Astrophysical Journal
Solar magnetic flux rope (MFR) plays a central role in the physics of coronal mass ejections (CMEs). It mainly includes a cold filament at typical chromospheric temperatures (∼10,000 K) and a hot channel at high coronal temperatures (∼10 MK).

AMT Astronomy Predictions: The Geometric Solutions to Solar System Anomalies

Standard cosmology assumes the universe is expanding. Accelerated Mass Theory (AMT)v11 proposes the inverse: the universe is static, but the 5th-dimensional scale of matter isundergoing a continuous collapse (Vshrink). This “Scale Collapse” creates a fundamental viscosityin the vacuum—a “flow” of space that generates what we perceive as gravity ...

A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.

Dam Regulation Moderates Climate‐Induced Rice Yield Loss in the Mekong‐Tonle Sap Lake System

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Rice, a principal global staple crop, is increasingly threatened by flooding under climate change, placing rice‐dependent economies at risk. Yet the capacity of human activities to mitigate inundation impacts on rice remains insufficiently quantified.

Numerical Investigations of Low‐Latitude Ground Magnetic Fields Due To Cavity Mode Oscillations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Pi2 oscillations are known to be associated with cavity mode oscillations (CMOs) in the inner magnetosphere at low latitudes. CMOs can also be excited by interplanetary shocks on the dayside. We present results from a global linear MHD wave model in spherical coordinates that allows us to analyze these waves at equatorial latitudes.

Quantum Astronomy: The Atomic Structure of the Solar System By Yerzhan Orymbetov

ABSTRACT Quantum Astronomy proposes that the Solar System is a macroscopic analogue of an atom.The Sun functions as a proton-scale central mass, containing 99.7% of the system’s totalmaterial—mirroring how the nucleus of an atom contains 99.9% of mass.

The Daily Atmospheric Ionospheric Limb Imager (DAILI) CubeSat Experiment

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Daily Atmospheric Ionospheric Limb Imager (DAILI) (Daily Atmospheric and Ionospheric Limb Imager) mission utilized a 6U CubeSat, deployed at about 410 km altitude in a 51‐degree orbit, to make simultaneous daytime limb measurements in two colors; at 630 nm to measure the OI (630 nm) redline and at 765 nm to measure the O2 ${\mathrm{O}}_{2}$

On the Effects of the Solar Wind Structure in the Global Distribution of dBH/dt ${\text{dB}}_{H}/\text{dt}$ Spikes During Geomagnetic Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Variations in the solar wind, particularly those associated with interplanetary coronal mass ejections (ICMEs) and high‐speed streams (HSSs), drive geomagnetic disturbances that produce rapid changes in the ground magnetic field. These variations, commonly quantified by the time derivative of the horizontal magnetic field dBH/dt $\left({\text ...

Medium‐Scale Traveling Ionospheric Disturbances Induced by Secondary Gravity Waves Associated With Record‐Breaking Heavy Rainfall in August 2021 Over Kyushu, Japan

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract This study reconstructs a multistep gravity wave (GW) pathway, from the generation of primary GWs by deep convection in the troposphere to the generation of secondary GWs that drive semi‐concentric medium‐scale traveling ionospheric disturbances (MSTIDs) in the ionosphere, during the record‐breaking heavy rainfall over Kyushu, Japan, in August
