Simulations of the Evolving Ozone Layer: Implications for the Early Earth, Exoplanets, and the Search For Life

Akhil Kumar, Gregory J. Cooke

Over 4 billion years, Earth's atmosphere has been transformed from a composition devoid of molecular oxygen (O) to one where O is now 21% of our modern atmosphere by volume…

Detecting habitable exoplanet atmospheres with LIFE, the Large Interferometer for Exoplanets

Sarah Rugheimer, Aiden Weatherbee, James Fecanin +21

A key goal of astronomers with the next generation telescopes is to detect signs of life in exoplanet atmospheres. NASA's next flagship is the Habitable Worlds Observatory (HWO). I…

Ecological modelling of hycean worlds

Gregory J. Cooke, Nikku Madhusudhan, Emily G. Mitchell

New observations are opening the possibility of characterising habitable environments in exoplanetary systems, with the recent example of the candidate hycean world K2-18 b. This m…

Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager

Vincent Van Eylen, Richard Massey, Saeeda Awan +167

Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…

Exploring the Sub-Neptune Frontier with JWST

Nikku Madhusudhan, Måns Holmberg, Savvas Constantinou +1

Sub-Neptune planets, with sizes and masses between those of Earth and Neptune, dominate the exoplanet population. Sub-Neptunes are expected to be the most diverse family of the exo…

A Systematic Search for Trace Molecules in the Atmosphere of Exoplanet K2-18 b

Lorenzo Pica-Ciamarra, Nikku Madhusudhan, Gregory J. Cooke +2

The first transmission spectrum of the habitable-zone sub-Neptune K2-18 b with JWST has opened a new avenue for atmospheric characterisation of temperate low-mass exoplanets. The o…

Considerations for Photochemical Modeling of Possible Hycean Worlds

Gregory J. Cooke, Nikku Madhusudhan

JWST is revolutionising the study of temperate sub-Neptunes, starting with the first detection of carbon-bearing molecules in the habitable-zone sub-Neptune K2-18 b. The retrieved…
