The Sensitivity of Eclipse Mapping to Planetary Rotation

open access: yesThe Astronomical Journal, 2022
Mapping exoplanets across phases and during secondary eclipse is a powerful technique for characterizing Hot Jupiters in emission. Since these planets are expected to rotate about axes normal to their orbital planes, with rotation periods synchronized ...

Tidal Dissipation Regimes among the Short-period Exoplanets

open access: yesThe Astrophysical Journal Letters, 2023
The efficiency of tidal dissipation provides a zeroth-order link to a planet’s physical properties. For super-Earth and sub-Neptune planets in the range R _⊕ ≲ R _p ≲ 4 R _⊕ , particularly efficient dissipation (i.e., low tidal quality factors) may ...

exoMMR: A New Python Package to Confirm and Characterize Mean Motion Resonances

open access: yesThe Astronomical Journal, 2023
The study of orbital resonances allows for the constraint of planetary properties of compact systems. We can predict a system’s resonances by observing the orbital periods of the planets, as planets in or near mean motion resonance (MMR) have period ...

Rocky Planet or Water World? Observability of Low-density Lava World Atmospheres

open access: yesThe Astrophysical Journal, 2023
Super-Earths span a wide range of bulk densities, indicating a diversity in interior conditions beyond that seen in the solar system. In particular, an emerging population of low-density super-Earths may be explained by volatile-rich interiors.

Characterizing the Atmospheric Dynamics of HD 209458b-like Hot Jupiters Using AI-driven Image Recognition/Categorization

open access: yesThe Astrophysical Journal, 2023
In order to understand the results of recent observations of exoplanets, models have become increasingly complex. Unfortunately, this increases both the computational cost and output size of said models.

Photochemical Hazes Dramatically Alter Temperature Structure and Atmospheric Circulation in 3D Simulations of Hot Jupiters

open access: yesThe Astrophysical Journal, 2023
Photochemical hazes are expected to form in hot Jupiter atmospheres and may explain the strong scattering slopes and muted spectral features observed in the transmission spectra of many hot Jupiters.

The Radius Cliff is a Waterfall: Explaining Sub-Neptune Exoplanets with Steam Worlds

open access: yesThe Astrophysical Journal
The demographics of Kepler planets provide a key testbed for models of planet formation and evolution, particularly for explaining the radius valley separating super-Earths and sub-Neptunes.

Earth as a Transiting Exoplanet: A Validation of Transmission Spectroscopy and Atmospheric Retrieval Methodologies for Terrestrial Exoplanets

open access: yesThe Planetary Science Journal, 2023
The James Webb Space Telescope (JWST) will enable the search for and characterization of terrestrial exoplanet atmospheres in the habitable zone via transmission spectroscopy.

Design Considerations for Visualization Transitions of 3D Spatial Data in Hybrid AR‐Desktop Environments

open access: yesComputer Graphics Forum, EarlyView.
We present design considerations for animated transitions of the appearance of 3D spatial datasets in a hybrid Augmented Reality‐desktop context. Such hybrid interfaces combine both traditional and immersive displays to facilitate the exploration of 2D and 3D data representations in the environment in which they are best displayed.
