Planetary interiors

Eos, Transactions American Geophysical Union, 1971
Most publications on planetary interiors in the last 4 years have dealt with the moon, and the most popular topic has been the interpretation of lunar mascons (the nature and discovery of mascons are covered in the review ‘Selenodesy and Planetary Geodesy’ by W. M. Kaula).

Reaction between Hydrogen and Ferrous/Ferric Oxides at High Pressures and High Temperatures—Implications for Sub-Neptunes and Super-Earths

The Planetary Science Journal, 2023
Sub-Neptune exoplanets may have thick hydrogen envelopes and therefore develop a high-pressure interface between hydrogen and the underlying silicates/metals. Some sub-Neptunes may convert to super-Earths via massive gas loss.

Exploring the Largest Mass Fraction of the Solar System: the Case for Planetary Interiors [PDF]

, 2017
Why explore planetary interiors: The typical image that comes to mind for planetary science is that of a planet surface. And while surface data drive our exploration of evolved geologic processes, it is the interiors of planets that hold the key to ...

Helium Depletion in Escaping Atmospheres of Sub-Neptunes: A Signature of Primary-to-secondary Transition

The Astrophysical Journal
Short-period sub-Neptunes are common in extrasolar systems. These sub-Neptunes are generally thought to have primary atmospheres of protoplanetary-disk gas origin.

Apophis planetary defense campaign [PDF]

, 2022
We describe results of a planetary defense exercise conducted during the close approach to Earth by the near-Earth asteroid (99942) Apophis during 2020 December–2021 March. The planetary defense community has been conducting observational campaigns since

Eddy-driven Zonal Jet Flows in the Laboratory

Comptes Rendus. Physique
Zonal jets are a ubiquitous feature of the circulation of planetary atmospheres, oceans and interiors. Many of the dynamical mechanisms that lead to the formation and evolution of such jets can be reproduced and studied in laboratory experiments, which ...

An Object‐Oriented Bayesian Gravity Inversion Scheme for Inferring Density Anomalies in Planetary Interiors

Earth and Space Science, 2023
Gravity inversions have contributed greatly to our knowledge of the interior of planetary bodies and the processes that shaped them. However, previous global gravity inversion methods neglect the inference of mantle density anomalies when using ...

Theoretical evidence of H-He demixing under Jupiter and Saturn conditions

Nature Communications
The immiscibility of hydrogen-helium mixture under the temperature and pressure conditions of planetary interiors is crucial for understanding the structures of gas giant planets (e.g., Jupiter and Saturn).
