The Heating Efficiency of Hot Jupiters from a Data-driven Perspective
The Astronomical JournalThe inflated radii of hot Jupiters have been explored by various theoretical mechanisms. By connecting planetary thermal evolution models with the observed properties of hot Jupiters using hierarchical Bayesian models, a theoretical parameter called the ...

Geological Journal, Volume 61, Issue 7, Page 1976-2001, July 2026.Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

THERMODYNAMICS OF ATMOSPHERIC CIRCULATION ON HOT JUPITERS [PDF]
The Astrophysical Journal, 2009 Atmospheric circulation on tidally-locked exoplanets is driven by the absorption and reradiation of heat from the host star. They are natural heat engines, converting heat into mechanical energy. A steady state is possible only if there is a mechanism to dissipate mechanical energy, or if the redistribution of heat is so effective that the Carnot ...

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

Functional Stability and the Limits of 16S‐Based Inference in Serpentine Biocrusts
Ecological Research, Volume 41, Issue 4, July 2026.Serpentine geochemistry and moisture regime shape bacterial biocrust communities in the Barberton Greenstone Belt, South Africa. While coarse taxonomic metrics (alpha and beta diversity) showed no significant differences, ASV‐level analyses revealed strong taxonomic shifts linked to soil chemistry and moisture, with numerous serpentine‐associated taxa ...

Hot Jupiter secondary eclipses measured by Kepler
EPJ Web of Conferences, 2011 Hot-Jupiters are known to be dark in visible bandpasses, mainly because of the alkali metal absorption features. The outstanding quality of the Kepler mission photometry allows a detection (or non-detection upper limits on) giant planet secondary ...

Saving Doomed Planets: Mass Loss and Angular Momentum Return Boost Hot Jupiter Survival Rates
The Astrophysical JournalThe existence of giant extrasolar planets on short-period orbits (“hot Jupiters”) challenges planet formation theories because such planets are difficult to form close to the star.
