Equation of State of Iron and Iron Sulfide with Implications for Jupiter’s Galilean Satellites

Introduction

 Jupiter's four Galilean satellites (Io, Europa, Ganymede, and Callisto) have been the focus of intense interest as a result of the recent Galileo spacecraft mission to this system. These four satellites are large bodies (Table 1). The Jovian system can, in many respects, be considered a miniature version of our own solar system. Among the most intriguing findings from the Galileo mission are the possibility of a liquid ocean on Europa and the likelihood that a geodynamo is present on Ganymede (and possibly other satellites as well).
