Abstract
Large uncertainties in the current estimated densities or all of these
satellites prevent detailed modeling or predictions. Nevertheless, current
evidence suggests that at least Titania and Oberon might have "anomalously"
high densities (2-3 g cm^)-3)), possibly requiring almost ice-free hydrated silicates
or formation in a CO-rich environment, implying presence or co-clathrate
and a small ice/rock ratio. Triton and the four largest satellites or Uranus
are massive enough to have undergone significant accretional heating and early
differentiation; NH_3-H_2O volcanism; partial outgassing or CO, N_2, CH_4; formation
or dark surficial deposits or carbon-rich material obtained by UV irradiation
or outgassed material; and, at least in the cases or Ariel and Triton,
a possibility or weak ongoing icy volcanic activity. Triton may be the largest
captured body in the solar system, with an unusual history and composition,
including the possibility or substantial liquid or solid nitrogen obtained from
either primordial NH_3 photolysis or clathrate decomposition.
