Neutral Wind Control of Jupiter's Non‐Auroral Ionosphere

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract We use JAMMIES (JAMMIES is Another Model Making Ionospheric EStimates), a new model of Jupiter's non‐auroral ionosphere, to demonstrate that neutral wind‐driven field‐aligned plasma transport can explain decades of measurements inconsistent with a solar‐dominated ionosphere. Two observations highlight these inconsistencies: a minimum in H3+ ${\

Giant planet formation in the solar system [PDF]

The formation history of Jupiter has been of interest due to its ability to shape the solar system's history. Yet little attention has been paid to the formation and growth of Saturn and the other giant planets.

NIRCam Yells at Cloud: JWST MIRI Imaging Can Directly Detect Exoplanets of the Same Temperature, Mass, Age, and Orbital Separation as Saturn and Jupiter

The Astrophysical Journal Letters
NIRCam and MIRI coronagraphy has successfully demonstrated the ability to directly image young sub-Jupiter-mass and mature gas giant exoplanets. However, these modes struggle to reach the sensitivities needed to find the population of cold giant planets ...

Inside the Fire Plume Chemical Interactions: A Review on Key Processes and Future Directions

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Fire plumes are rising columns of heated air masses, consisting of gaseous and particulate matter generated by combustion, affecting air quality, climate and public health. The chemical species released undergo secondary reactions and participate in chemical and physical interactions, altering the properties of the fire plume.

Effects of Outer Giant Planets on In Situ Formation of Inner Super-Earths

The Astrophysical Journal
Recent studies have found an observational correlation between the presence of outer giant planets and inner super-Earths, which implies that outer giants do not suppress the formation of super-Earths.

Significance of Size‐Dependent Hygroscopicity Parameterization for Aerosol‐Cloud Interactions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Aerosol‐cloud interactions (aerosol indirect effects) are the most significant source of uncertainties in the effective radiative forcing (ERF) due to aerosols which can act as cloud condensation nuclei (CCN). Uncertainties in the indirect effect can result from systematic uncertainties in aerosol water uptake (hygroscopicity).

Tidal Dissipation in Stably Stratified and Semiconvective Regions of Rotating Giant Planets: Incorporating Coriolis Forces

The Astrophysical Journal, 2023
We study how stably stratified or semiconvective layers alter tidal dissipation rates associated with the generation of inertial, gravito-inertial, interfacial, and surface gravity waves in rotating giant planets.

Magnetic Field Disturbance Induced by the Enhanced Suprathermal Ring Current in the Magnetosphere of Saturn

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Saturn's ring current, which modulates the global magnetic field configuration, varies dynamically with hot plasma injections. However, quantifying transient magnetic field disturbances remains challenging in the absence of in situ measurements on Saturn's surface.

Life at the end of worlds : modelling the biosignatures of microbial life in diverse environments at the end of the habitable lifetimes of Earth-like planets [PDF]

, 2014
This thesis investigates how increased global mean temperatures on Earth, induced by the increase in the luminosity of the Sun as it ages, change the types of habitable environments on the planet at local scales over the next 3 Gyr.

The Evolution of Jupiter and Saturn as a Function of the Rρ Parameter

The Astrophysical Journal
Computed using the APPLE planetary evolution code, we present updated evolutionary models for Jupiter and Saturn that incorporate helium rain, nonadiabatic thermal structures, and “fuzzy” extended heavy-element cores.
