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 ...

New progresses in basic geological theories and future exploration domains of natural gas in China
Natural Gas Industry B, 2018 As natural gas exploration expands to deep, ultra-deep and unconventional areas, more and more complex exploration targets are encountered. In this circumstance, it is necessary to improve the existing basic natural gas geological theories for guiding ...

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.

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
