Separating gas-giant and ice-giant planets by halting pebble accretion [PDF]
Astronomy & Astrophysics, 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.

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 ...

An ultrahot gas-giant exoplanet with a stratosphere [PDF]
Nature, 2017 Infrared radiation emitted from a planet contains information about the chemical composition and vertical temperature profile of its atmosphere. If upper layers are cooler than lower layers, molecular gases will produce absorption features in the ...

Journal of Natural Gas Geoscience, 2019 Deepwater exploration has been developed for more than 40 years since 1975; generally, its exploration history can be divided into the beginning stage (1975–1984), the early stage (1985–1995) and the rapid development stage (1996-now).

Disk evolution, element abundances and cloud properties of young gas giant planets. [PDF]
Life (Basel), 2014 We discuss the chemical pre-conditions for planet formation, in terms of gas and ice abundances in a protoplanetary disk, as function of time and position, and the resulting chemical composition and cloud properties in the atmosphere when young gas giant

MASSIVE SATELLITES OF CLOSE-IN GAS GIANT EXOPLANETS [PDF]
The Astrophysical Journal, 2009 We study the orbits, tidal heating and mass loss from satellites around close-in gas giant exoplanets. The focus is on large satellites which are potentially observable by their transit signature. We argue that even Earth-size satellites around hot Jupiters may be immune to destruction by orbital decay; detection of such a massive satellite would ...

A desert of gas giant planets beyond tens of au [PDF]
, 2016 Direct imaging observations constrain the fraction of stars orbited by gas giant planets with separations greater than 10 au to about 0.01 only. This is widely believed to indicate that massive protoplanetary discs rarely fragment on planetary mass ...
