Fluid Dynamics Experiments for Planetary Interiors [PDF]

Surveys in Geophysics, 2021
AbstractUnderstanding fluid flows in planetary cores and subsurface oceans, as well as their signatures in available observational data (gravity, magnetism, rotation, etc.), is a tremendous interdisciplinary challenge. In particular, it requires understanding the fundamental fluid dynamics involving turbulence and rotation at typical scales well beyond

A High-pressure Filled Ice in the H2O–CO2–CH4 System, with Possible Consequences for the CO2–CH4 Biosignature Pair

The Astrophysical Journal, 2023
Here we constrain the speciation of carbon that may outgas in ocean exoplanets. Ocean exoplanets likely have at least a few percent by mass of water, which is sufficient to build a high-pressure ice layer between a rocky interior and the outer ...

Probing the Interiors of Very Hot Jupiters Using Transit Light Curves [PDF]

, 2009
Accurately understanding the interior structure of extra-solar planets is critical for inferring their formation and evolution. The internal density distribution of a planet has a direct effect on the star-planet orbit through the gravitational ...

VARIATIONAL PRINCIPLE FOR PLANETARY INTERIORS [PDF]

The Astrophysical Journal, 2016
ABSTRACT In the past few years, the number of confirmed planets has grown above 2000. It is clear that they represent a diversity of structures not seen in our own solar system. In addition to very detailed interior modeling, it is valuable to have a simple analytical framework for describing planetary structures.

Evolution of a Water-rich Atmosphere Formed by a Giant Impact on an Earth-sized Planet

The Astrophysical Journal, 2023
The atmosphere of a terrestrial planet that is replenished with secondary gases should have accumulated hydrogen-rich gas from its protoplanetary disk.

Signatures of Planets in Spatially Unresolved Disks [PDF]

, 2005
Main sequence stars are commonly surrounded by debris disks, composed of cold dust continuously replenished by a reservoir of undetected dust-producing planetesimals. In a planetary system with a belt of planetesimals (like the Solar System's Kuiper Belt)

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 ...

Constraining the Venus Interior Structure with Future VERITAS Measurements of the Gravitational Atmospheric Loading

The Planetary Science Journal, 2023
The complex dynamics of the Venus atmosphere produces a periodic mass redistribution pattern that creates a time-variable modulation of the gravity field of Venus.
