Nightside Clouds on Tidally-locked Terrestrial Planets Mimic Atmosphere-Free Scenarios
Diana Powell, Robin Wordsworth, Karin Öberg
We investigate the impact of nightside cloud formation on the observable night-day contrast of tidally-locked terrestrial planet atmospheres. We demonstrate that, in the case where…
Sulphur dioxide in the mid-infrared transmission spectrum of WASP-39b
Diana Powell, Adina D. Feinstein, Elspeth K. H. Lee +70
The recent inference of sulphur dioxide (SO) in the atmosphere of the hot (1100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations suggests that phot…
Debris Disks can Contaminate Mid-Infrared Exoplanet Spectra: Evidence for a Circumstellar Debris Disk around Exoplanet Host WASP-39
Laura Flagg, Alycia J. Weinberger, Taylor J. Bell +21
The signal from a transiting planet can be diluted by astrophysical contamination. In the case of circumstellar debris disks, this contamination could start in the mid-infrared and…
Two-Dimensional Models of Microphysical Clouds on Hot Jupiters I: Cloud Properties
Diana Powell, Xi Zhang
We present a new two-dimensional, bin-scheme microphysical model of cloud formation in the atmospheres of hot Jupiters that includes the effects of longitudinal gas and cloud trans…
Nightside clouds and disequilibrium chemistry on the hot Jupiter WASP-43b
Taylor J. Bell, Nicolas Crouzet, Patricio E. Cubillos +80
Hot Jupiters are among the best-studied exoplanets, but it is still poorly understood how their chemical composition and cloud properties vary with longitude. Theoretical models pr…
