The impending opacity challenge in exoplanet atmospheric characterization

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 ...

Deep radio interferometric search for decametre radio emission from the exoplanet Tau Boötis b

Astronomy & Astrophysics
Detection of electron cyclotron maser (ECM) emission from exoplanets in the 10-40 MHz radio band is likely the only way to measure an exoplanet's magnetic field directly. However, no definitive detection of exoplanetary ECM emission has been made to date.
