Sea Ice as an Origin of Life Location for Hycean and Ocean Worlds
Edouard F. L. Barrier, Nikku Madhusudhan, Frances E. Rigby
Water worlds with potential deep oceans are at the forefront of currently observable exoplanetary habitability. The standard requirements for habitability are the presence of an en…
General Circulation Models of Hycean Worlds
Edouard Barrier, Nikku Madhusudhan
Sub-Neptunes represent the current frontier of exoplanet atmospheric characterisation. A proposed subset, Hycean planets, would have liquid water oceans and be potentially habitabl…
A new convection scheme for GCMs of temperate sub-Neptunes
Edouard F. L. Barrier, Nikku Madhusudhan
Atmospheric characterisation of temperate sub-Neptunes is the new frontier of exoplanetary science with recent JWST observations of possible Hycean world K2-18b. Accurate modelling…
Chemical Conditions on Hycean Worlds
Nikku Madhusudhan, Julianne I. Moses, Frances Rigby +1
Traditionally, the search for life on exoplanets has been predominantly focused on rocky exoplanets. Hycean worlds are a class of habitable sub-Neptunes with planet-wide oceans and…
