Exoplanetary Geophysics -- An Emerging Discipline

, 2015
Thousands of extrasolar planets have been discovered, and it is clear that the galactic planetary census draws on a diversity greatly exceeding that exhibited by the solar system's planets.

Constraints on the Long-term Existence of Dilute Cores in Giant Planets

The Planetary Science Journal
Post-Cassini ring seismology analysis suggests the existence of a stable stratification inside Saturn that extends from the center to ∼60% of its radius, in what is recognized today as Saturn’s dilute core.

On the Migration of Jupiter and Saturn: Constraints from Linear Models of Secular Resonant Coupling with the Terrestrial Planets

, 2011
We examine how the late divergent migration of Jupiter and Saturn may have perturbed the terrestrial planets. We identify six secular resonances between the nu_5 apsidal eigenfrequency of Jupiter and Saturn and the four eigenfrequencies of the ...

Penetrative Convection in Rotating Tilted f-plane with Multiple Radiative and Convective Layers

The Astrophysical Journal
In this paper, we conducted a linear instability analysis to investigate penetrative convection in rotating, tilted f -planes with multiple convectively stable and unstable layers. Our findings indicate that penetrative distance decreases with increasing

Elemental ratios in stars vs planets

, 2015
Context. The chemical composition of planets is an important constraint for planet formation and subsequent differentiation. While theoretical studies try to derive the compositions of planets from planet formation models in order to link the composition

On the Meaning of the Dynamo Radius in Giant Planets with Stable Layers

The Astrophysical Journal
Current structure models of Jupiter and Saturn suggest that helium becomes immiscible in hydrogen in the outer part of the planets’ electrically conducting regions.

Giant impacts in the Saturnian System: a possible origin of diversity in the inner mid-sized satellites

, 2011
It is widely accepted that Titan and the mid-sized regular satellites around Saturn were formed in the circum-Saturn disk. Thus, if these mid-sized satellites were simply accreted by collisions of similar ice-rock satellitesimals in the disk, the ...

Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534 b

The Astrophysical Journal Letters
We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534 b, the first transiting planet known to orbit a white dwarf (WD) star.

The JWST Weather Report from the Isolated Exoplanet Analog SIMP 0136+0933: Pressure-dependent Variability Driven by Multiple Mechanisms

The Astrophysical Journal Letters
Isolated planetary-mass objects share their mass range with planets but do not orbit a star. They lack the necessary mass to support fusion in their cores and thermally radiate their heat from formation as they cool, primarily at infrared wavelengths ...

Jupiter Evolutionary Models Incorporating Stably Stratified Regions

The Astrophysical Journal
We address the issue of which broad set of initial conditions for the planet Jupiter best matches the current presence of a “fuzzy core” of heavy elements, while at the same time comporting with measured parameters such as its effective temperature ...
