Stable stratification of the helium rain layer yields vastly different interiors and magnetic fields for Jupiter and Saturn
Steve Markham, Tristan Guillot
At sufficiently high pressures (~Mbar) and low temperatures (~1e3-1eK), hydrogen and helium become partly immiscible. Interpretations of Jupiter and Saturn's magnetic fields favor…

Three-dimensional atmospheric dynamics of Jupiter from ground-based Doppler imaging spectroscopy in the visible
François-Xavier Schmider, Patrick Gaulme, Raúl Morales-Juberías +25
We present three-dimensional (3D) maps of Jupiter's atmospheric circulation at cloud-top level from Doppler-imaging data obtained in the visible domain with JIVE, the second node o…

On the hypothesis of an inverted Z-gradient inside Jupiter
Saburo Howard, Tristan Guillot, Steve Markham +6
Models of Jupiter s interior struggle to agree with measurements of the atmospheric composition. Interior models favour a subsolar or solar abundance of heavy elements Z while atmo…
