The Nature of Gas Giant Planets
, 2023 Revealing the true nature of the gas giant planets in our Solar System is challenging. The masses of Jupiter and Saturn are about 318 and 95 Earth masses, respectively. While they mostly consist of hydrogen and helium, the total mass and distribution of the heavier elements, which reveal information on their origin, are still unknown.

THE ORBITAL EVOLUTION OF GAS GIANT PLANETS AROUND GIANT STARS [PDF]
The Astrophysical Journal, 2009 Recent surveys have revealed a lack of close-in planets around evolved stars more massive than 1.2 Msun. Such planets are common around solar-mass stars. We have calculated the orbital evolution of planets around stars with a range of initial masses, and have shown how planetary orbits are affected by the evolution of the stars all the way to the tip ...

Influence of Compositional Gradient Effect on Tight Condensate Gas Reservoir Development
Geofluids, 2022 Condensate gas is a transition fluid between oil and gas, which is sensitive to the reservoir temperature and pressure. In condensate gas reservoir, especially in the moderate-giant one, fluid composition often varies with depth.

Sodium and Potassium Signatures of Volcanic Satellites Orbiting Close-in Gas Giant Exoplanets [PDF]
Astrophysical Journal, 2019 Extrasolar satellites are generally too small to be detected by nominal searches. By analogy to the most active body in the solar system, Io, we describe how sodium (Na i) and potassium (K i) gas could be a signature of the geological activity venting ...

Detection of a westward hotspot offset in the atmosphere of hot gas giant CoRoT-2b [PDF]
, 2018 Short-period planets exhibit day–night temperature contrasts of hundreds to thousands of kelvin. They also exhibit eastward hotspot offsets whereby the hottest region on the planet is east of the substellar point1; this has been widely interpreted as ...

From Planetesimal to Planet in Turbulent Disks. II. Formation of Gas Giant Planets [PDF]
Astrophysical Journal, 2018 In the core accretion scenario, gas giant planets are formed form solid cores with several Earth masses via gas accretion. We investigate the formation of such cores via collisional growth from kilometer-sized planetesimals in turbulent disks.

Changes in the metallicity of gas giant planets due to pebble accretion [PDF]
, 2018 We run numerical simulations to study the accretion of gas and dust grains onto gas giant planets embedded into massive protoplanetary discs. The outcome is found to depend on the disc cooling rate, planet mass, grain size and irradiative feedback from ...

Restrictions on the Growth of Gas Giant Cores via Pebble Accretion [PDF]
Astrophysical Journal, 2018 We apply an order-of-magnitude model of gas-assisted growth, known as pebble accretion, in a turbulent medium to suggest a reason why some systems form wide orbital separation gas giants while others do not. In contrast to traditional growth by ballistic
