  author={Gabriel Tobie and Olivier Grasset and Jonathan I. Lunine and Antoine Mocquet and Christophe Sotin},
Through coupled thermal and orbital calculations including a full description of tidal dissipation, heat transfer and the H 2O–NH3 phase diagram, we propose a model for the internal structure and composition of Titan testable with Cassini–Huygens measurements. The high value of Titan’s orbital eccentricity provides a strong constraint on the amount of the tidal energy dissipation on its surface and within its interior since its formation. We show that only models with a few percent of ammonia…

Structural and tidal models of Titan and inferences on cryovolcanism
Titan, Saturn's largest satellite, is subject to solid body tides exerted by Saturn on the timescale of its orbital period. The tide-induced internal redistribution of mass results in tidal stress
Titan’s internal structure and the evolutionary consequences
Titan’s moment of inertia (MoI), estimated from the quadrupole gravity field measured by the Cassini spacecraft, is 0.342, which has been interpreted as evidence of a partially differentiated
The density structure of Titan’s outer ice shell
Abstract We use the recent models of Titan’s shape and gravity to estimate the large-scale density structure of its outer ice shell. We assume that the bottom boundary of the ice shell is an
Physico-chemical models of the internal structure of partially differentiated Titan
We analyze models of the internal structure of Titan, a large icy satellite of the Saturn system. Calculations are carried out using information on the mass, mean density, moment of inertia, orbital
Titan’s internal structure inferred from its gravity field, shape, and rotation state
Abstract Several quantities measured by the Cassini-Huygens mission provide insight into the interior of Titan: the second-degree gravity field coefficients, the shape, the tidal Love number, the
Titan's Interior Structure
The goal of this chapter is to give a description of Titan's interior that is consistent with the new constraints provided by the Cassini mission. As the Cassini mission proceeds into its first
New insights on Titan's interior from its obliquity
We constructed a 6-degrees of freedom rotational model of Titan as a 3-layer body consisting of a rigid core, a fluid global ocean, and a floating ice shell. The ice shell exhibits
Does Titan’s long-wavelength topography contain information about subsurface ocean dynamics?
Abstract The long-wavelength topography of Titan is characterized by relatively small amplitudes (about 1 km peak to peak), an anomalous equatorial bulge (the poles are about 300 m lower than the
Structure and dynamics of Titan’s outer icy shell constrained from Cassini data
Abstract The Cassini–Huygens mission has brought evidence for an internal ocean lying beneath an outer icy shell on Titan. The observed topography differs significantly from the reference hydrostatic
Effect of internal gravitational coupling on Titan's non‐synchronous rotation
[1] Variations in the spin period of Titan have been detected by the Cassini radar observations. Angular momentum exchange between Titan's surface and the atmosphere over seasonal time scales


Interior structure models and tidal Love numbers of Titan
[1] Interior models of a differentiated Titan with an internal ammonia-water ocean and chondritic radiogenic heat production in an undifferentiated rock + iron core have been calculated. We assume
On the internal structure and dynamics of Titan
Abstract The purpose of this paper is to study the evolution of Titan from the primordial core overturn to the present, and to investigate the possible existence of both a deep liquid layer and an
The Cooling Rate of a Liquid Shell in Titan's Interior
Models describing the evolution of the primordial liquid layer in Titan's interior are presented using parameterized models. These models incorporate recent experimental data on the ammonia water
Tidal Dissipation on Titan
Abstract Tidal dissipation may constrain the nature of the surface and interior of Titan. Provided the surface of Titan is covered by satellite-wide hydrocarbon seas and oceans, the solid body of
Internal structure and dynamics of the large icy satellites
Abstract The magnetic data returned by the Galileo mission suggest that deep oceans are present within the icy Galilean satellites. In addition, tectonic features on Europa are consistent with models
Thermal convection in the outer shell of large icy satellites
Evolution of large icy satellites is controlled by heat transfer across the outer ice I layer. After the core overturn a possible structure consists of a silicate core and a shell of molten ices. As
Tidally heated convection: Constraints on Europa's ice shell thickness
[1] The thickness of Europa's ice shell is constrained with numerical experiments of thermal convection, including heterogeneous tidal heating. Thermal convection occurs in the stagnant lid regime
Oceans in the icy Galilean satellites of Jupiter
Abstract Equilibrium models of heat transfer by heat conduction and thermal convection show that the three satellites of Jupiter—Europa, Ganymede, and Callisto—may have internal oceans underneath ice
Thermal evolution of a differentiated Ganymede and implications for surface features
Thermal evolution models are presented for Ganymede, assuming a mostly differentiated initial state of a water ocean overlying a rock layer. The only heat sources are assumed to be primordial heat
Tidal effects of disconnected hydrocarbon seas on Titan
It is argued that a more realistic topography, in which liquid hydrocarbons are confined to a number of disconnected seas or crater lakes, may satisfy both the dynamical and observational constraints.
