Jupiter Evolutionary Models Incorporating Stably Stratified Regions

open access: yesThe 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 ...

Characterizing Cold Giant Planets in Reflected Light: Lessons from 50 Years of Outer Solar System Exploration and Observation

open access: yes, 2014
A space based coronagraph, whether as part of the WFIRST/AFTA mission or on a dedicated space telescope such as Exo-C or -S, will be able to obtain photometry and spectra of multiple gas giant planets around nearby stars, including many known from radial

Formation and Evolution Simulations of Saturn, Including Composition Gradients and Helium Immiscibility

open access: yesThe Planetary Science Journal
In this paper, the formation of Saturn is modeled by detailed numerical simulations according to the core-nucleated accretion scenario. Previous models are enhanced to include the dissolution of accreting planetesimals, composed of water ice, rock, and ...

Formation of terrestrial planets in eccentric and inclined giant-planet systems

open access: yes, 2016
International audienceThe orbits of extrasolar planets are more various than the circular and coplanar ones of the Solar system. We study the impact of inclined and eccentric massive giant planets on the terrestrial planet formation process. The physical

Searching for gas giant planets on Solar system scales - a NACO/APP L′-band survey of A- and F-type main-sequence stars [PDF]

open access: yes, 2017
We report the results of a direct imaging survey of A- and F-type main-sequence stars searching for giant planets. A/F stars are often the targets of surveys, as they are thought to have more massive giant planets relative to solar-type stars.

Hydrodynamical modelling of tidal dissipation in gas giant planets at the time of space missions

open access: yes, 2023
Gas giant planets are differentially rotating magnetic objects that have strong and complex interactions with their environment. In our Solar system, they interact with their numerous moons while exoplanets with very short orbital periods (hot Jupiters),

Influence of Penetration Depth on Jets on Giant Planets: Equatorial Jet Direction, Jet Numbers, and Jet Energy Fraction

open access: yesThe Planetary Science Journal
It remains puzzling why, despite their similar nature, Jupiter and Saturn possess a prograde equatorial jet, whereas Uranus and Neptune have a retrograde one.

Heavy element enrichment of the gas giant planets

open access: yes, 2008
According to both spectroscopic measurements and interior models, Jupiter, Saturn, Uranus and Neptune possess gaseous envelopes that are enriched in heavy elements compared to the Sun.

7. Rocks on other planets

open access: yes, 2016
Rocks are not just an Earthly phenomenon. They make up the surfaces of some of the planets of the solar system and, in one form or another, those all of the many moons, innumerable comets, and other small objects that orbit out to great distances from ...
