Empirical Models of Pressure and Density in Saturn's Interior: Implications for the Helium Concentration, its Depth Dependence, and Saturn's Precession Rate
Ravit Helled, Gerald Schubert, John D. Anderson
We present 'empirical' models (pressure vs. density) of Saturn's interior constrained by the gravitational coefficients J_2, J_4, and J_6 for different assumed rotation rates of th…
Core Formation in Giant Gaseous Protoplanets
Ravit Helled, Gerald Schubert
Sedimentation rates of silicate grains in gas giant protoplanets formed by disk instability are calculated for protoplanetary masses between 1 M_Saturn to 10 M_Jupiter. Giant proto…
Grain Sedimentation in a Giant Gaseous Protoplanet
Ravit Helled, Morris Podolak, Attay Kovetz
We present a calculation of the sedimentation of grains in a giant gaseous protoplanet such as that resulting from a disk instability of the type envisioned by Boss (1998). Boss (1…
Planetesimal Capture in the Disk Instability Model
Ravit Helled, Morris Podolak, Attay Kovetz
We follow the contraction and evolution of a typical Jupiter-mass clump created by the disk instability mechanism, and compute the rate of planetesimal capture during this evolutio…
