Early Release Science of the exoplanet WASP-39b with JWST NIRCam
Measuring the metallicity and carbon-to-oxygen (C/O) ratio in exoplanet atmospheres is a
fundamental step towards constraining the dominant chemical processes at work and, if in …

Planet Mass and Metallicity: The Exoplanets and Solar System Connection
Theoretical studies of giant planet formation suggest that substantial quantities of metals—
elements heavier than hydrogen and helium—can be delivered by solid accretion during the …

Compositional imprints in density–distance–time: a rocky composition for close-in low-mass exoplanets from the location of the valley of evaporation
We use an end-to-end model of planet formation, thermodynamic evolution, and
atmospheric escape to investigate how the statistical imprints of evaporation depend on the …

Beyond equilibrium temperature: how the atmosphere/interior connection affects the onset of methane, ammonia, and clouds in warm transiting giant planets
The atmospheric pressure–temperature profiles for transiting giant planets cross a range of
chemical transitions. Here we show that the particular shapes of these irradiated profiles for …

ACCESS: a featureless optical transmission spectrum for WASP-19b from Magellan/IMACS
ABSTRACT The short-period (0.94-d) transiting exoplanet WASP-19b is an exceptional
target for transmission spectroscopy studies, due to its relatively large atmospheric scale …
