Pressures in the hydrospheres of large ocean worlds extend to ranges exceeding those in
Earth deepest oceans. In this regime, dense water ices and other high-pressure phases …

The Cassini-Huygens mission that explored the Saturn system during the period 2004–2017
revolutionized our understanding of Titan, the only known moon with a dense atmosphere …

Massive and water-rich planets should be ubiquitous in the universe. Many of these worlds
are expected to be subject to important irradiation from their host star, and display …

Context. Water is one of the key chemical elements in planetary structure modelling. Due to
its complex phase diagram, equations of state often only cover parts of the pressure …

The radius valley (or gap) in the observed distribution of exoplanet radii, which separates
smaller super-Earths from larger sub-Neptunes, is a key feature that theoretical models must …

Exoplanet exploration has revealed that many—perhaps most—terrestrial exoplanets
formed with substantial H2-rich envelopes, seemingly in contrast to solar system terrestrials …

The two primary observable quantities of an exoplanet—its mass and radius—alone are not
sufficient to probe a rocky exoplanet's interior composition and mineralogy. To overcome …

We report the discovery and characterization of two transiting planets around the bright M1 V
star LP 961-53 (TOI-776, J= 8.5 mag, M= 0.54±0.03 M⊙) detected during Sector 10 …

Sodium chloride is expected to be found on many of the surfaces of icy moons like Europa
and Ganymede. However, spectral identification remains elusive as the known NaCl …

This Review presents the state of knowledge of the thermophysical properties of water in all
its phases and the reference formulations that provide standardized, recommended values …
