On the Radii of Close-in Giant Planets [PDF]
The Astrophysical Journal, 2000 The recent discovery that the close-in extrasolar giant planet, HD209458b, transits its star has provided a first-of-its-kind measurement of the planet's radius and mass. In addition, there is a provocative detection of the light reflected off of the giant planet, $ $ Boo b.

On the Radii of Extrasolar Giant Planets [PDF]
The Astrophysical Journal, 2003 We have computed evolutionary models for extrasolar planets which range in mass from 0.1 to 3.0 Jovian Masses, and which range in equilibrium temperature from 113 K to 2000 K. We present four sequences of models, designed to show the structural effects of a solid core and of internal heating due to the conversion of kinetic to thermal energy at ...

In Situ exploration of the giant planets [PDF]
Experimental 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.

Warm giant exoplanet characterisation: current state, challenges and outlook
Frontiers 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

, 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
The 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]
The 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
The 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
The 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 ...
