Revealing giant planet interiors beneath the cloudy veil
Nature Communications, 2020 Observations from the Juno and Cassini missions provide essential constraints on the internal structures and compositions of Jupiter and Saturn, resulting in profound revisions of our understanding of the interior and atmospheres of Gas Giant planets ...

The Astrophysical Journal, 2023 Thanks to “dust-to-planet” simulations (DTPSs), which treat the collisional evolution directly from dust to giant-planet cores in a protoplanetary disk, we showed that giant-planet cores are formed in ≲10 au in several 10 ^5 yr, because porous pebbles ...

Petroleum Science, 2017 There are rich oil and gas resources in marine carbonate strata worldwide. Although most of the oil and gas reserves discovered so far are mainly distributed in Mesozoic, Cenozoic, and upper Paleozoic strata, oil and gas exploration in the Proterozoic ...

Giant Planet Accretion and Migration: Surviving the Type I Regime [PDF]
Astrophys.J. 644 (2006) 1214-1222, 2006 In the standard model of gas giant planet formation, a large solid core (~ 10 times the Earth's mass) forms first, then accretes its massive envelope (100 or more Earth masses) of gas. However, inward planet migration due to gravitational interaction with the proto-stellar gas disk poses a difficulty in this model. Core-sized bodies undergo rapid "Type

Natural Gas Liberations around Production Wells at Russian Arctic Gas Fields
Geosciences, 2020 Gas samples from gas liberations around wellheads on two giant natural gas fields in West Siberia (Bovanenkovo and Yamburg) have been tested for their carbon isotopic and molecular compositions. Results have shown local, microbial genesis of gas and that

Oligarchic and giant impact growth of terrestrial planets in the presence of gas giant planet migration [PDF]
Astron.Astrophys.441:791-806,2005, 2005 We present the results of N--body simulations which examine the effect that gas giant planet migration has on the formation of terrestrial planets. The models incorporate a 0.5 Jupiter mass planet undergoing type II migration through an inner protoplanet--planetesimal disk, with gas drag included.

Restrictions on the Growth of Gas Giant Cores via Pebble Accretion [PDF]
, 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 collisions with planetesimals, growth by pebble accretion is not necessarily limited by doubling ...

Quantifying External Energy Inputs for Giant Planet Magnetospheres
Geophysical Research LettersThe long‐standing “energy crisis” at the giant planets refers to the anomalous heating of planetary thermospheres compared to the available energy from solar irradiance. The coupling between planetary magnetospheres and their upper atmospheres is thought
