JWST/NIRISS reveals the water-rich "steam world" atmosphere of GJ 9827 d

Caroline Piaulet-Ghorayeb, Bjorn Benneke, Michael Radica +30

With sizable volatile envelopes but smaller radii than the solar system ice giants, sub-Neptunes have been revealed as one of the most common types of planet in the galaxy. While t…

Constraining Background N2 Inventories on Directly Imaged Terrestrial Exoplanets to Rule Out O2 False Positives

Sawyer Hall, Joshua Krissansen-Totton, Tyler Robinson +2

Direct imaging spectroscopy with future space-based telescopes will constrain terrestrial planet atmospheric composition and potentially detect biosignature gases. One promising in…

The Case and Context for Atmospheric Methane as an Exoplanet Biosignature

Maggie A. Thompson, Joshua Krissansen-Totton, Nicholas Wogan +2

Methane has been proposed as an exoplanet biosignature. Imminent observations with the James Webb Space Telescope may enable methane detections on potentially habitable exoplanets,…

Understanding planetary context to enable life detection on exoplanets and test the Copernican principle

Joshua Krissansen-Totton, Maggie Thompson, Max L. Galloway +1

The search for life on exoplanets is motivated by the universal ways in which life could modify its planetary environment. Atmospheric gases such as oxygen and methane are promisin…
