Out on a Limb: The Signatures of East-West Asymmetries in Transmission Spectra from General Circulation Models
Kenneth E. Arnold, Arjun B. Savel, Eliza M. -R. Kempton +5
In the era of JWST, observations of hot Jupiter atmospheres are becoming increasingly precise. As a result, the signature of limb asymmetries due to temperature or abundance differ…
The radiative effects of photochemical hazes on the atmospheric circulation and phase curves of sub-Neptunes
Maria E. Steinrueck, Vivien Parmentier, Laura Kreidberg +13
Measuring the atmospheric composition of hazy sub-Neptunes like GJ~1214b through transmission spectroscopy is difficult because of the degeneracy between mean molecular weight and…
