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

Impact of Gas Giant Instabilities on Habitable Planets [PDF]
arXiv, 2018 The detection of many extrasolar gas giants with high eccentricities indicates that dynamical instabilities in planetary systems are common. These instabilities can alter the orbits of gas giants as well as the orbits of terrestrial planets and therefore eject or move a habitable planet out of the habitable zone.

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.

Formation of giant planets with large metal masses and metal fractions via giant impacts in a rapidly dissipating disk [PDF]
A&A 648, L1 (2021), 2021 According to planetary interior models, some giant planets contain large metal masses with large metal-mass fractions. HD 149026b and TOI-849b are characteristic examples of these giant planets. It has been suggested that the envelope mass loss during giant impacts plays a key role in the formation of such giant planets.

The Astronomical Journal, 2023 We confirm the planetary nature of two gas giants discovered by TESS to transit M dwarfs with stellar companions at wide separations. TOI-3984 A ( J = 11.93) is an M4 dwarf hosting a short-period (4.353326 ± 0.000005 days) gas giant ( M _p = 0.14 ± 0.03 ...

Separating gas-giant and ice-giant planets by halting pebble accretion [PDF]
A&A 572, A35 (2014), 2014 In the Solar System giant planets come in two flavours: 'gas giants' (Jupiter and Saturn) with massive gas envelopes and 'ice giants' (Uranus and Neptune) with much thinner envelopes around their cores. It is poorly understood how these two classes of planets formed.

Giants are bullies: how their growth influences systems of inner sub-Neptunes and super-Earths [PDF]
A&A 674, A178 (2023), 2023 Observations point to a correlation between outer giants and inner sub-Neptunes, unexplained by simulations so far. We utilize N-body simulations including pebble and gas accretion as well as planetary migration to investigate how the gas accretion rates influence the formation of systems of inner sub-Neptunes and outer gas giants as well as the ...
