Exoplanetary atmospheres—chemistry, formation conditions, and habitability

N Madhusudhan, M Agúndez, JI Moses, Y Hu - Space science reviews, 2016 - Springer
Characterizing the atmospheres of extrasolar planets is the new frontier in exoplanetary
science. The last two decades of exoplanet discoveries have revealed that exoplanets are …

Detection of Fe i in the atmosphere of the ultra-hot Jupiter WASP-121b, and a new likelihood-based approach for Doppler-resolved spectroscopy

Model atmospheres of irradiated exoplanets: the influence of stellar parameters, metallicity, and the C/O ratio

P Mollière, R van Boekel, C Dullemond… - The Astrophysical …, 2015 - iopscience.iop.org
Many parameters constraining the spectral appearance of exoplanets are still poorly
