Double superionicity in icy compounds at planetary interior conditions [PDF]
Nature Communications, 2023 The elements hydrogen, carbon, nitrogen and oxygen are assumed to comprise the bulk of the interiors of the ice giant planets Uranus, Neptune, and sub-Neptune exoplanets.

A Reanalysis of the Composition of K2-106b: An Ultra-short-period Super-Mercury Candidate
The Astronomical Journal, 2023 We present a reanalysis of the K2-106 transiting planetary system, with a focus on the composition of K2-106b, an ultra-short-period, super-Mercury candidate. We globally model existing photometric and radial velocity data and derive a planetary mass and

Relation of Gravity, Winds, and the Moment of Inertia of Jupiter and Saturn
The Planetary Science Journal, 2023 We study the relationship of zonal gravity coefficients, J _2 _n , zonal winds, and axial moment of inertia (MoI) by constructing models for the interiors of giant planets.

The Astrophysical Journal, 2023 Jupiter’s atmosphere interior is a coupled fluid dynamical system strongly influenced by the rapid background rotation. While the visible atmosphere features east–west zonal winds on the order of ∼100 m s ^−1 , zonal flows in the dynamo region are ...

Magnesium oxide-water compounds at megabar pressure and implications on planetary interiors
Nature Communications, 2023 Magnesium Oxide and water are abundant in the interior of planets. Here, the authors predict three new MgO-H2O compounds: Mg2O3H2, MgO3H4 and MgO4H6, and they exhibit superionic behavior in planetary interior conditions.

The Planetary Science Journal, 2023 Clathrate hydrates may represent a sizable fraction of material within the icy shells of Kuiper Belt objects and icy moons. They influence the chemical and thermal evolution of subsurface oceans by locking volatiles into the ice shell and by providing ...

Dynamical Measurements of the Interior Structure of Exoplanets [PDF]
, 2013 Giant gaseous planets often reside on orbits in sufficient proximity to their host stars for the planetary quadrupole gravitational field to become non-negligible. In presence of an additional planetary companion, a precise characterization of the system'

The Effects of Rotation Rate on Deep Convection in Giant Planets with Small Solid Cores [PDF]
, 2006 We study how the pattern of thermal convection and differential rotation in the interior of a giant gaseous planet is affected by the presence of a small solid core as a function of the planetary rotation rate.

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 ...
