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

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