Formation of Titan in Saturn's subnebula: constraints from Huygens probe measurements

Alibert, Y.; Mousis, O.

We present an evolutionary turbulent model of the Saturn's subnebula consistent with recent core accretion formation models of Saturn. Our calculations are similar to those conducted in the case of the Jovian subnebula, and take into account the vertical structure of the disk, as well as the evolution of its surface density, as given by an α-disk …

Clathrate hydrates as a sink of noble gases in Titan's atmosphere

Mousis, O.; Thomas, C.; Picaud, S. +1 more

We use a statistical thermodynamic approach to determine the composition of clathrate hydrates which may form from a multiple compound gas whose composition is similar to that of Titan's atmosphere. Assuming that noble gases are initially present in this gas phase, we calculate the ratios of xenon, krypton and argon to species trapped in clathrate…
