Warm Jupiter Tidal Migration Can Spare Inner Planets; Hot Jupiter Tidal Migration May Not
The Astrophysical JournalIn this work, we investigate the dynamical survival of short-period inner planets during the high-eccentricity tidal migration of companion exterior giant planets.

Clouds and Hazes in GJ 1214 b’s Metal-rich Atmosphere
The Astronomical JournalThe 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 ...

Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects
The Astrophysical JournalSmall planets (≲1 M _⊕ ) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and ...

Early Time Small-scale Structures in Hot Exoplanet Atmosphere Simulations
The Astrophysical JournalWe 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.
