Query: Sulfurization of Iron in the Dynamic Solar Nebula and Implications for
  Planetary Compositions   One explanation for the enhanced ratio of volatiles to hydrogen in Jupiter's
atmosphere compared to a a gas of solar composition is that the planet accreted
volatile-bearing clathrates during its formation. Models, however, suggest that
S would be over abundant if clathrates were the primary carrier of Jupiter's
volatiles. This led to the suggestion that S was depleted in the outer nebula
due to the formation troilite (FeS). Here, this depletion is quantitatively
explored by modeling the coupled dynamical and chemical evolution of Fe grains
in the solar nebula. It is found that disks that undergo rapid radial expansion
from an initially compact state may allow sufficient production of FeS and
carry H$_{2}$S-depleted gas outward where ices would form, providing the
conditions needed for S-depleted clathrates to form. However, this expansion
would also carry FeS grains to this region, which could also be incorporated
into planetesimals. Thus for clathrates to be a viable source of volatiles,
models must account for the presence of both H$_{2}$S in FeS in the outer solar
nebula.
