Models of Saturn's interior: Evidence for phase separation

Research output: Contribution to journalArticlepeer-review

Abstract

Models of Saturn's interior have been constructed based on an accumulation picture of planet formation. It was found that central pressures were ∼90 Mb, and central temperatures ∼10K. In sharp contrast to Jupiter, which requires large amounts of heavy material in the envelope to match the observed gravitational quadrupole moment, Saturn requires an almost solar envelope. Indeed, the ratio of enhanced material in the envelope to material in the core is less than ∼0.1, while the corresponding value for Jupiter is ∼2.
