“Follow the water!” The solar system is full of water in different states, from the Sun’s water vapor to the ice of Pluto and beyond. Water is not only linked […]

From Super-Earths to Sub-Neptunes: Observational Constraints and Connections to Theoretical Models
We update the PlanetS catalog of transiting planets with precise and robust mass and radius measurements and use this comprehensive catalog to explore Mass-Radius (M-R) diagrams.
Potential Surface Ice Distribution On Close-in Terrestrial Exoplanets Around M dwarfs
Previous studies suggested that surface ice could be distributed on close-in terrestrial exoplanets around M-dwarfs if heat redistribution on the planets is very inefficient.
Distinguishing Potential Organic Biosignatures on Ocean Worlds from Abiotic Geochemical Products using Thermodynamic Calculations
The search for life in our solar system often involves efforts to detect organic molecules, which have been found on many extraterrestrial bodies, including planets, moons, meteorites, comets, and asteroids. […]
Biogenic Sulfur Gases As Biosignatures On Temperate Sub-Neptune Waterworlds
Theoretical predictions and observational data indicate a class of sub-Neptune exoplanets may have water-rich interiors covered by hydrogen-dominated atmospheres. Provided suitable climate conditions, such planets could host surface liquid oceans.
On The Ocean Conditions Of Hycean Worlds
Recent studies have suggested the possibility of Hycean worlds, characterised by deep liquid water oceans beneath H2-rich atmospheres.
Eccentricity Distribution Beyond the Snow Line and Implications for Planetary Habitability
A fundamental question in the study of planetary system demographics is: how common is the solar system architecture?
Can One Hear Supercontinents In The Tides Of Ocean Planets?
Recent observations and theoretical progress made about the history of the Earth-Moon system suggest that tidal dissipation in oceans primarily drives the long term evolution of orbital systems hosting ocean […]
Between Outer Space And Antarctica: Miniature Robots To Carry Out Research Below The Ice
For years, scientists have assumed that there are oceans of water beneath the ice covers on the moons Enceladus and Europa. Even in outer space, the presence of water can […]
Where Are The Water Worlds?: Self-Consistent Models of Water-Rich Exoplanet Atmospheres
It remains to be ascertained whether sub-Neptune exoplanets primarily possess hydrogen-rich atmospheres or whether a population of H2O-rich “water worlds” lurks in their midst.
