The Eclipse-map** Null Space: Comparing Theoretical Predictions with Observed Maps

RC Challener, E Rauscher - The Astronomical Journal, 2023 - iopscience.iop.org
High-precision exoplanet eclipse light curves, like those possible with JWST, enable flux

The effect of interior heat flux on the atmospheric circulation of hot and ultra-hot Jupiters

TD Komacek, P Gao, DP Thorngren… - The Astrophysical …, 2022 - iopscience.iop.org
Many hot and ultra-hot Jupiters have inflated radii, implying that their interiors retain
significant entropy from formation. These hot interiors lead to an enhanced internal heat flux …

Bringing 2D eclipse map** out of the shadows with leave-one-out cross validation

RC Challener, L Welbanks, P McGill - The Astronomical Journal, 2023 - iopscience.iop.org
Eclipse map** is a technique for inferring 2D brightness maps of transiting exoplanets
from the shape of an eclipse light curve. With JWST's unmatched precision, eclipse map** …

Warm Jupiters Beyond the Tidal Synchronization Limit may Exhibit a Wide Range of Secondary Eclipse Depths

E Rauscher, NB Cowan, R Luger - The Astronomical Journal, 2023 - iopscience.iop.org
With the JWST we can now characterize the atmospheres of longer-orbit planets, but this
moves us into a regime where we cannot assume that tidal forces from the star have eroded …

ThERESA: three-dimensional eclipse map** with application to synthetic JWST data

RC Challener, E Rauscher - The Astronomical Journal, 2022 - iopscience.iop.org
Spectroscopic eclipse observations, like those possible with the James Webb Space
