Giant Planets [PDF]

open access: yes, 2007
We review the interior structure and evolution of Jupiter, Saturn, Uranus and Neptune, and giant exoplanets with particular emphasis on constraining their global composition. Compared to the first edition of this review, we provide a new discussion of the atmospheric compositions of the solar system giant planets, we discuss the discovery of ...

Giant planets seismology [PDF]

open access: yesSymposium - International Astronomical Union, 1997
The giant planets Jupiter and Saturn belong to the interesting category of possible goals for remote seismic analysis. Their first seismic observations and their analysis were attempted in 1987 and 1991 respectively, under Philippe Delache's initiative.

Spin Dynamics of Extrasolar Giant Planets in Planet–Planet Scattering [PDF]

open access: yesThe Astrophysical Journal, 2021
Abstract Planet–planet scattering best explains the eccentricity distribution of extrasolar giant planets, and past literature showed that the orbits of planets evolve due to planet–planet scattering. This work studies the spin evolution of planets in planet–planet scattering in two-planet systems.

Rapid Formation of Gas-giant Planets via Collisional Coagulation from Dust Grains to Planetary Cores. II. Dependence on Pebble Bulk Density and Disk Temperature

open access: yesThe Astrophysical Journal, 2023
Thanks to “dust-to-planet” simulations (DTPSs), which treat the collisional evolution directly from dust to giant-planet cores in a protoplanetary disk, we showed that giant-planet cores are formed in ≲10 au in several 10 ^5 yr, because porous pebbles ...

Takeout and Delivery: Erasing the Dusty Signature of Late-stage Terrestrial Planet Formation

open access: yesThe Astrophysical Journal, 2023
The formation of planets like Earth is expected to conclude with a series of late-stage giant impacts that generate warm dusty debris, the most anticipated visible signpost of terrestrial planet formation in progress.

DISK-FED GIANT PLANET FORMATION [PDF]

open access: yesThe Astrophysical Journal Letters, 2016
ABSTRACT Massive giant planets, such as the ones being discovered by direct imaging surveys, likely experience the majority of their growth through a circumplanetary disk. We argue that the entropy of accreted material is determined by boundary layer processes, unlike the “cold-” or “hot-start” hypotheses usually invoked in the core ...

Giant Planet Lightning in Nonideal Gases

open access: yesThe Planetary Science Journal, 2023
Lightning has been directly observed or inferred on all giant planets, generally accepted to be occurring in their water clouds. However, much as Earth has both cloud–cloud and cloud–ground lightning, this does not mean all flashes occur in a narrow ...

Memoirs of a Giant Planet [PDF]

open access: yesThe Astrophysical Journal, 2019
Abstract Saturn is ringing weakly. Exquisite data from the Cassini mission reveal the presence of f-mode oscillations as they excite density waves in Saturn’s rings. These oscillations have displacement amplitudes of order 1 m on Saturn’s surface. We propose that they result from large impacts in the past. Experiencing little dissipation
