Clouds and Hazes in GJ 1214 b’s Metal-rich Atmosphere

The Astronomical Journal
The sub-Neptune GJ 1214 b has an infamously flat transmission spectrum, likely due to thick aerosols in its atmosphere. A recent JWST/MIRI spectroscopic phase curve of GJ 1214 b added to this picture, suggesting a highly reflective and metal-rich ...

Early Time Small-scale Structures in Hot Exoplanet Atmosphere Simulations

The Astrophysical Journal
We report on the critical influence of small-scale flow structures (e.g., fronts, vortices, and waves) that immediately arise in hot exoplanet atmosphere simulations initialized with a resting state.

Up, Up, and Away: Winds and Dynamical Structure as a Function of Altitude in the Ultrahot Jupiter WASP-76b

The Astrophysical Journal
Due to the unprecedented signal strengths offered by the newest high-resolution spectrographs on 10 m class telescopes, exploring the 3D nature of exoplanets is possible with an unprecedented level of precision.

Kepler-discovered Multiple-planet Systems near Period Ratios Suggestive of Mean-motion Resonances Are Young

The Astronomical Journal
Before the launch of the Kepler Space Telescope, models of low-mass planet formation predicted that convergent type I migration would often produce systems of low-mass planets in low-order mean-motion resonances.

Observational Signatures of a Previous Dynamical Instability in Multi-planet M-dwarf Systems

The Astrophysical Journal
We identify observational signatures suggesting a history of dynamical instability in 26 out of 34 M-dwarf multi-planet systems containing no large planets.
