Comparing Jupiter interior structure models to Juno gravity measurements and the role of a dilute core
S. M. Wahl,William B. Hubbard,Burkhard Militzer,Tristan Guillot,Yamila Miguel,Naor Movshovitz,Naor Movshovitz,Yohai Kaspi,Ravit Helled,Ravit Helled,Daniel R. Reese,Eli Galanti,Steven Levin,John E. P. Connerney,Scott Bolton +14 more
TL;DR: In this paper, a selection of interior models based on ab initio computer simulations of hydrogen-helium mixtures is presented. But, the model predictions are strongly affected by the chosen equation of state, the prediction of an enrichment of Z in the deep, metallic envelope over that in the shallow, molecular envelope holds.
Journal ArticleDOI
Jupiter's atmospheric jet streams extend thousands of kilometres deep.

Folkner,Ravit Helled,Andrew P. Ingersoll,Steven Levin,Jonathan I. Lunine,Yamila Miguel,Yamila Miguel,Burkhard Militzer,Marzia Parisi,S. M. Wahl +21 more
TL;DR: It is reported that the measured odd gravitational harmonics J3, J5, J7 and J9 indicate that the observed jet streams extend down to depths of thousands of kilometres beneath the cloud level, probably to the region of magnetic dissipation at a depth of about 3,000 kilometres.
Journal ArticleDOI
A suppression of differential rotation in Jupiter’s deep interior
Tristan Guillot,Yamila Miguel,Yamila Miguel,Burkhard Militzer,William B. Hubbard,Yohai Kaspi,Eli Galanti,Hao Cao,Hao Cao,Ravit Helled,S. M. Wahl,Luciano Iess,W. M. Folkner,D. J. Stevenson,Jonathan I. Lunine,Daniel R. Reese,A. Biekman,Marzia Parisi,Daniele Durante,John E. P. Connerney,Steven Levin,Scott Bolton +21 more
TL;DR: It is found that the deep interior of the planet rotates nearly as a rigid body, with differential rotation decreasing by at least an order of magnitude compared to the atmosphere, making it fully consistent with the constraints obtained independently from the odd gravitational harmonics.
Journal ArticleDOI
Measurement and implications of Saturn's gravity field and ring mass.
Luciano Iess,Burkhard Militzer,Yohai Kaspi,P. D. Nicholson,Daniele Durante,P. Racioppa,A. Anabtawi,Eli Galanti,William B. Hubbard,Mirco Junior Mariani,Paolo Tortora,S. M. Wahl,Marco Zannoni +12 more
TL;DR: The results show that Saturn's rings are substantially younger than the planet itself and constrain models of their origin, and five small moons located in and around the rings are presented, confirming that the flows are very deep and likely extend down to the levels where magneticipation occurs.
Journal ArticleDOI
Measurement of Jupiter’s asymmetric gravity field
Luciano Iess,W. M. Folkner,Daniele Durante,Marzia Parisi,Yohai Kaspi,Eli Galanti,Tristan Guillot,William B. Hubbard,D. J. Stevenson,John D. Anderson,Dustin Buccino,L. Gomez Casajus,Andrea Milani,Ryan S. Park,P. Racioppa,Daniele Serra,Paolo Tortora,Marco Zannoni,Hao Cao,Ravit Helled,Jonathan I. Lunine,Yamila Miguel,Burkhard Militzer,S. M. Wahl,John E. P. Connerney,Steven Levin,Scott Bolton +26 more
TL;DR: Measurements of Jupiter’s gravity harmonics are reported through precise Doppler tracking of the Juno spacecraft in its polar orbit around Jupiter, finding a north–south asymmetry, which is a signature of atmospheric and interior flows.
