Breaking Degeneracies in Formation Histories by Measuring Refractory Content in Gas Giants
The Astrophysical Journal, 2023 Relating planet formation to atmospheric composition has been a long-standing goal of the planetary science community. So far, most modeling studies have focused on predicting the enrichment of heavy elements and the C/O ratio in giant planet atmospheres.

Long-term Stability of Planetary Systems Formed from a Transitional Disk
The Astrophysical Journal, 2023 Transitional disks are protoplanetary disks with large and deep central holes in the gas, possibly carved by young planets. Dong & Dawson simulated systems with multiple giant planets that were capable of carving and maintaining such gaps during the disk

The significance of coal-derived gas in major gas producing countries
Petroleum Exploration and Development, 2019 The core of coal-derived gas theory is that coal measure is the gas source, and the hydrocarbon generation of coal measure is dominated by gas and supplemented by oil, so discoveries in related basins are dominated by gas fields.

Atmospheric Chemistry in Giant Planets, Brown Dwarfs, and Low-Mass Dwarf Stars III. Iron, Magnesium, and Silicon [PDF]
, 2010 We use thermochemical equilibrium calculations to model iron, magnesium, and silicon chemistry in the atmospheres of giant planets, brown dwarfs, extrasolar giant planets (EGPs), and low-mass stars.

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.

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 ...

The mass of gas giant planets: Is Saturn a failed gas giant?
Astronomy & Astrophysics, 2023 The formation history of giant planets inside and outside the Solar System remains unknown. We suggest that runaway gas accretion is initiated only at a mass of ∼100 M⊕ and that this mass corresponds to the transition to a gas giant, a planet whose composition is dominated by hydrogen and helium.
