Interior Structure of Jupiter & Saturn
Models based on the following article:
Guillot T., 1999, ``A
comparison of the interiors of Jupiter and Saturn", Plan. Space Sci.47,
1183-1200 [ps
file]
The next link will lead you to ASCII files representing the interior
structure of Jupiter and Saturn. The models match all observational constraints
(as of 1999), in particular the planets' radius and gravitational moments.
Only a few example models are available.
The files have the following structure:
* Parameters of the model. What to look for:
PPT: T -> First order molecular/metallic
transition (rho & S discontinuity)
F -> Interpolated molecular/metallic transition (continuous)
X: Mass mixing ratio of hydrogen in
the molecular envelope (Y+Z~1-X)
DX=X(metallic)-X(molecular): Compositional
discontinuity at the molecular/metallic transition
Mcoeur: Core mass (as a fraction of
the total mass of the planet)
frac_glace: Fraction of "ices" in
the core (the rest being "rocks")
Rayon moyen: Mean radius of the planet
in cm
Req, J2, J4, J6, J8: Equatorial radius
and gravitational moments
* Number of layers (integer)
* Various quantities in cgs units (generally log(X)).
Gradc, Grada and Gradr are the convective, adiabatic and radiative gradients,
respectively
* Number of layers (integer)
* Various quantities in cgs units (generally X).
(Mass of Jupiter = 1.8986E+30 g)
(Mass of Saturn = 5.68464E+29 g)
