Interior and Evolution of the Giant Planets

open access: yesRemote Sensing, 2023
The giant planets were the first to form and hold the key to unveiling the solar system’s formation history in their interiors and atmospheres.

Warm giant exoplanet characterisation: current state, challenges and outlook

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The characterisation of giant exoplanets is crucial to constrain giant planet formation and evolution theory and for putting the solar-system’s giant planets in perspective. Typically, mass-radius (M-R) measurements of moderately irradiated warm Jupiters

In Situ exploration of the giant planets [PDF]

open access: yesExperimental Astronomy, 2021
AbstractRemote sensing observations suffer significant limitations when used to study the bulk atmospheric composition of the giant planets of our Solar System. This impacts our knowledge of the formation of these planets and the physics of their atmospheres.

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 ...

Hot Jupiters Have Giant Companions: Evidence for Coplanar High-eccentricity Migration

open access: yesThe Astrophysical Journal Letters, 2023
This study considers the characteristics of planetary systems with giant planets based on a population-level analysis of the California Legacy Survey planet catalog. We identified three characteristics common to hot Jupiters (HJs).

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

Inner Planetary System Gap Complexity is a Predictor of Outer Giant Planets

open access: yesThe Astronomical Journal, 2023
The connection between inner small planets and outer giant planets is crucial to our understanding of planet formation across a wide range of orbital separations. While Kepler provided a plethora of compact multiplanet systems at short separations (≲1 au)

TOI-4600 b and c: Two Long-period Giant Planets Orbiting an Early K Dwarf

open access: yesThe Astrophysical Journal Letters, 2023
We report the discovery and validation of two long-period giant exoplanets orbiting the early K dwarf TOI-4600 ( V = 12.6, T = 11.9), first detected using observations from the Transiting Exoplanet Survey Satellite (TESS) by the TESS Single Transit ...

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

open access: yesThe 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.

Formation of Giant Planets [PDF]

open access: yes, 2018
Giant planets are tens to thousands of times as massive as the Earth, and many times as large. Most of their volumes are occupied by hydrogen and helium, the primary constituents of the protostellar disks from which they formed. Significantly, the solar system giants are also highly enriched in heavier elements relative to the Sun, indicating that ...
