Scaling of Latitude‐Dependent Heat Transport in Geostrophic Convection

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Latitudinal variations in heat transport shape the thermal and magnetic evolution of rapidly rotating planets, stars, and icy moons. Although global simulations have revealed strong equatorial–polar contrasts, a predictive scaling theory has been lacking.

Giant planets: Clues on current and past organic chemistry in the outer solar system [PDF]

The giant planets of the outer solar system - Jupiter, Saturn, Uranus, and Neptune - were formed in the same flattened disk of gas and dust, the solar nebula, as the terrestrial planets were.

Steady Collapse of Uranus' Exosphere After 1998 to the Present Decade

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Uranus' thermospheric temperature decreased from ∼800K in 1986 to ∼450K in 2022 as determined from observations of H3+ and H2 infrared emissions. Spitzer 2007 lower atmosphere observations do not emulate this cooling trend. Here we show that the atomic H Lyman ⍺ emission from the disk of Uranus observed by HST from 2011 to 2022 are not ...

Temperatures of Jupiter’s Upper Atmosphere: The Role of the Planetary Magnetic Field

The Astrophysical Journal Letters
The primary source of heating in the upper atmospheres (thermospheres) of giant planets has been the subject of long debate. The conundrum (or “energy crisis”) consists in observed thermosphere temperatures at low and midlatitudes exceeding values ...

Jupiter's Decisive Role in the Inner Solar System's Early Evolution [PDF]

, 2015
The statistics of extrasolar planetary systems indicate that the default mode of planet formation generates planets with orbital periods shorter than 100 days, and masses substantially exceeding that of the Earth.

Interfacial Atomic and Electronic Structures of LSM/YSZ Thin Films as Models for SOC Air Electrodes

ChemElectroChem, Volume 13, Issue 6, 17 March 2026.
Lanthanum–strontium manganite/yttria‐stabilized zirconia thin films serve as model systems for solid oxide cell electrodes, where high‐resolution scanning transmission electron microscopy and X‐ray photoelectron spectroscopy reveal atomistic interfacial features and electronic structure supported by atomistic modeling of these interfaces.

Jupiter’s Interior with an Inverted Helium Gradient

The Planetary Science Journal
Jupiter’s gravity field observed by NASA’s Juno spacecraft indicates that the density in the 10–100 GPa region is lower than one would expect from a H/He adiabat with 0.5–5× solar water abundance, as has been observationally inferred in Jupiter’s ...

Carbon Dot–Directed Sustainable Defect Engineering in CoMoO4 for High‐Performance Supercapacitors

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Carbon dots (CDs) direct oxygen‐vacancy engineering in CoMoO4 via a solvent‐free mechanochemical route, enhancing surface area, electronic conductivity and electrochemical stability for high‐performance supercapacitors. Defect engineering via oxygen vacancy modulation represents a pivotal strategy in designing high‐performance electrode materials ...

The Linear Mixing Approximation in Silica–Water Mixtures at Planetary Conditions

The Astrophysical Journal
The linear mixing approximation (LMA) is often used in planetary models for calculating the equations of state (EOS) of mixtures. A commonly assumed planetary composition is a mixture of rock and water. Here we assess the accuracy of the LMA for pressure–

Equations of State, Thermodynamics, and Miscibility Curves for Jovian Planet and Giant Exoplanet Evolutionary Models

The Astrophysical Journal Supplement Series
The equation of state of hydrogen–helium (H–He) mixtures plays a vital role in the evolution and structure of gas giant planets and exoplanets. Recent equations of state that account for H–He interactions, coupled with H–He immiscibility curves, can now ...
