Analytic Modeling of Tidally Locked Rocky Planet Atmospheres across Dynamical Regimes
The Astrophysical JournalWe present a new first-principles analytic approach to interpreting eclipses and phase curves of rocky planets. Observations with JWST have reported nondetections of atmospheres around the majority of hot rocky planets orbiting M dwarfs. However, most of

Exoplanet Aeronomy: A Case Study of WASP-69 b’s Variable Thermosphere
The Astronomical JournalAeronomy, the study of Earth’s upper atmosphere and its interaction with the local space environment, has long traced changes in the thermospheres of Earth and other solar system planets to solar variability in the X-ray and extreme-ultraviolet ...

Tropical Cyclones on Tidally Locked Rocky Planets: Dependence on Rotation Period
The Astrophysical JournalTropical cyclones occur over the Earth’s tropical oceans, with characteristic genesis regions and tracks tied to the warm ocean surface that provide energy to sustain these storms.

Signature of Vertical Mixing in Hydrogen-dominated Exoplanet Atmospheres
The Astrophysical JournalVertical mixing is a crucial disequilibrium process in exoplanet atmospheres, significantly impacting chemical abundance and observed spectra. While current state-of-the-art observations have detected its signatures, the effect of vertical mixing on ...

The Astrophysical JournalIn an Earth-analogue atmosphere, water vapor is a key carrier of hydrogen in the lower atmosphere. The vertical transport of water to above the tropopause is one of the primary control valves on the atmospheric hydrogen escape rate.

The Astrophysical JournalWe present medium-wave (∼0.5–13 μ m) radiative flux distributions and spectra derived from high-resolution atmospheric dynamics simulations of an exoplanet, WASP-121 b. This planet serves to illustrate several important features.

Radiatively Active Clouds and Magnetic Effects Explored in a Grid of Hot Jupiter GCMs
The Astrophysical JournalCloud formation and magnetic effects are both expected to significantly impact the structures and observable properties of hot Jupiter atmospheres. For some hot Jupiters, thermal ionization and condensation can coexist in a single atmosphere, and both ...

Three-dimensional Ocean Dynamics and Detectability of Tidally Locked Lava Worlds
The Astrophysical JournalTidally locked lava planets are hot, rocky worlds on close-in orbits with a permanent molten dayside. With JWST, their surfaces and atmospheres are beginning to be revealed.

Coupled Planetary Interior and Tidal Evolution
The Astrophysical JournalWe present a new planetary structure/thermal evolution model, designed for use in problems that couple orbital dynamics with planetary structure. We first benchmark our structural/thermal evolution calculations against the MESA stellar evolution code ...
