A secondary atmosphere on the rocky exoplanet 55 Cancri e [PDF]

Nature
Characterizing rocky exoplanets is a central aim of astronomy, and yet the search for atmospheres on rocky exoplanets has so far resulted in either tight upper limits on the atmospheric mass1–3 or inconclusive results4–6.

Oxygen False Positives on Habitable Zone Planets Around Sun‐Like Stars

AGU Advances, 2021
Oxygen is a promising exoplanet biosignature due to the evolutionary advantage conferred by harnessing starlight for photosynthesis, and the apparent low likelihood of maintaining oxygen‐rich atmospheres without life.

Evidence for morning-to-evening limb asymmetry on the cool low-density exoplanet WASP-107 b [PDF]

Nature Astronomy
The atmospheric properties of hot exoplanets are expected to be different between the morning and the evening limbs due to their global atmospheric circulation.

The impending opacity challenge in exoplanet atmospheric characterization [PDF]

Nature Astronomy, 2022
With a new generation of observatories coming online this decade, the process of characterizing exoplanet atmospheres will need to be reinvented. Currently mostly on the instrumental side, characterization bottlenecks will soon appear at the models used ...
