Host: The Japanese Society for Planetary Sciences: Local Organizing Committee for 2006 Fall Meeting
Jupiter's core mass is one approach to revealing formation scenario of the Solar System. Planetary models, which are consistent with observational properties obtained from in situ measurements made by telescopes and spacecraft missions, suggest a central core of Jupiter should range from zero to ten times mass of the Earth (Saumon & Guillot, 2004). This extensive limit keeps our solar system veiled. It results from uncertainties of equation of state (EOS) for hydrogen under strict conditions of the inside of a giant gaseous planet, at high pressure and temperature.
Assuming EOS to be polytrope models, we analyzed interior structures of Jupiter and Saturn numerically. At this meeting, we'll discuss the effect and dependency of rocky cores on EOS (polytrope index).
