Jupiter and Saturn Rotation Periods

Anderson & Schubert (2007, Science, 317, 1384) proposed that Saturn’s rotation period can be ascertained by minimizing the dynamic heights of the 100 mbar isosurface with respect to the geoid; they derived a rotation period of 10h 32m 35s. We investigate the same approach for Jupiter to see if the Jovian rotation period is predicted by minimizing the dynamical heights of its isobaric (1 bar pre...

Interior models of Jupiter, Saturn and Neptune

Interior model calculations of Jupiter, Saturn and Neptune require EOS-data of hydrogen, helium and water in the regime of warm dense matter. In case of Saturn, the pressure in the deep interior rises up to 15 Mbar at 600010000 K and a hydrogen mass fraction of at least 40%. In Jupiter, due to his larger total mass compared to Saturn, the high-pressure region is more extended with pressures up ...

Whole Disk Observations of Jupiter, Saturn and Mars in Millimeter–Submillimeter Bands

Whole disk brightness ratios for Jupiter, Saturn, and Mars are reported at 5.7, 9.5, 16.4, and 22.5 cm. Using models for the brightness temperature of Mars, the whole disk brightness temperatures for Jupiter and Saturn are also given for the four frequencies. Subject headings: balloons — cosmic microwave background — infrared: solar system — planets and satellites: individual (Jupiter, Mars, Sa...

Comparative Evolution of Jupiter and Saturn

We present evolutionary sequences for Jupiter and Saturn, based on new nongray model atmospheres, which take into account the evolution of the solar luminosity and partitioning of dense components to deeper layers. The results are used to set limits on the extent to which possible interior phase separation of hydrogen and helium may have progressed in the two planets. When combined with static ...
