New Electron Population Trapped at Low Latitudes Near Jupiter

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We report observations of a low energy (<2 keV), trapped electron population near Jupiter's magnetic equator made by the Jovian Auroral Distributions Experiment (JADE) on Juno. Electron intensity peaks around the location of the minimum magnetic field magnitude along the field line that is connected to Juno.

Evidence of Free‐Bound Transitions in Warm Dense Matter and Their Impact on Equation‐of‐State Measurements

Contributions to Plasma Physics, Volume 66, Issue 7-8, September 2026.
ABSTRACT Warm dense matter (WDM) is now routinely created and probed in laboratories around the world, providing unprecedented insights into conditions achieved in stellar atmospheres, planetary interiors, and inertial confinement fusion experiments.

Microlensing search for extra solar planets [PDF]

, 2015
Gravitational microlensing may be used to probe distant stars for planetary companions. The presence of a planet in the vicinity of a star acting as the lens may cause a short lived anomaly in the observed lightcurve of the lensing event.

Burn Severity as a Driver of Multi‐Year Increases in Gross Primary Production and Solar‐Induced Fluorescence Following a Wildfire in Arctic Tundra

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract While climate‐driven increases in wildfires are altering the composition and function of Arctic ecosystems, the impact of burn severity on longer‐term changes in community composition and ecosystem fluxes remains less understood, creating uncertainty in estimates of the biome's carbon storage capacity.

The Detectability of Extreme CO2 Flux Events Using Atmospheric Observations

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract Climate events like droughts and floods perturb the carbon cycle and lead to extremes in CO2 fluxes (i.e., net biosphere exchange or NBE). These extreme NBE events are important because they contribute to inter‐annual variability in the global carbon cycle and may change in the future as climate changes.

Cyanobacteria Sustain Deep Ocean Carbon Sequestration Despite Eukaryotic Loss

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract The biological carbon pump exports phytoplankton‐derived organic carbon to the deep ocean, regulating long‐term carbon sequestration and climate. Yet how phytoplankton community composition controls the magnitude and efficiency of this process remains poorly understood.

Satellite‐Derived Volume Budget of Antarctic Sea Ice

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract In recent years, the Antarctic has seen a notable shift in sea ice trends: Where sea ice extent and volume were increasing on average, they have shown an unprecedented decline since 2016. Understanding the drivers of this shift is crucial to determining the impacts of climate change on sea ice and improving modeling of Antarctic sea ice ...

Assessing SWOT's Measurement Capabilities in the Complex Paraná River

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Estimating water surface elevation (WSE) is crucial for understanding hydrological processes; however, many rivers remain insufficiently monitored due to the limitations of in situ gauge networks. The Surface Water and Ocean Topography (SWOT) mission, equipped with Synthetic Aperture Radar technology, enables global monitoring of WSE with high

A Metric for Quantifying Spatial Heterogeneity in Gridded Atmospheric Fields

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Spatial heterogeneity influences many nonlinear atmospheric processes but it is often described qualitatively or with simple statistical measures that do not capture spatial organization. We introduce a mixing‐oriented metric for gridded fields based on the expected deviation of subdomain means from the global average.

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.
