A schematic diagram of the hycean Lotka-Volterra model we implement in this work. The schematic shows how various parameters in our model are connected in a vertical, one-dimensional water column.

Ecological Modelling Of Hycean Worlds

by Keith CowingMarch 25, 2026

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.

The comparison of reference sample with 𝐾𝑧𝑧 = 106 cm2 s−1 between GJ-176 and GJ-436. The difference between stars is not significant and only visible in the upper atmosphere, where UV flux has the biggest impact. It shows that for the purpose of our calculations, the choice of star is arbitrary, as long as it is the same stellar type. -- astro-ph.EP

Nitrogen Chemistry Of Hycean Worlds On The Example Of K2-18b

by Keith CowingSeptember 7, 2025September 7, 2025

A recent observation of the exoplanet K2-18b sparked interest among scientists – large amounts of carbon dioxide and methane were detected in an H2-rich background atmosphere.
