Evolution of steam worlds: energetic aspects
Artyom Aguichine, Natalie Batalha, Jonathan J. Fortney +3
Sub-Neptunes occupy an intriguing region of planetary mass-radius space, where theoretical models of interior structure predict that they could be water-rich, where water is in ste…
Jupiter's Interior with an Inverted Helium Gradient
Nadine Nettelmann, Jonathan J. Fortney
Jupiter's gravity field observed by NASA's Juno spacecraft indicates that the density in the 10--100 GPa region is lower than one would expect from a H/He adiabat with 0.5-5x solar…
H-HO demixing in Uranus and Neptune: Adiabatic structure models
Marina Cano Amoros, Nadine Nettelmann, Nicola Tosi +2
Demixing properties of planetary major constituents influence the interior structure and evolution of planets. Comparing experimental and computational data on the miscibility of h…
Atmospheric Helium Abundances in the Giant Planets
N. Nettelmann, M. Cano Amoros, N. Tosi +2
Noble gases are accreted to the giant planets as part of the gas component of the planet-forming disk. While heavier noble gases can separate from the evolution of the hydrogen-ric…
