Titan Through to the Core Gravity measurements acquired from orbiting spacecraft can provide useful information about the interior of planets and their moons. Iess et al. (p. 1367; see the Perspective by Sohl) used gravity data from four flybys of the Cassini spacecraft past Saturn's moon, Titan, to model the moon's gravity field and probe its deep interior structure. Their analysis implies that Titan is a partially differentiated body with a core consisting of a mix of ice and rock or hydrated… Expand
The Tides of Titan
Gravity data from six flybys of Saturn's moon, Titan, by the Cassini spacecraft suggest that Titan's interior is flexible on tidal time scales with the magnitude of the observed tidal deformations being consistent with the existence of a global subsurface water ocean. Expand

Evidence based on the analysis of its gravitational field that the interior of Titan was much colder than previously thought, and thereby impeded substantial melting and subsequent separation of the primordial ice-rock mixture is reported. Expand
Some features of rotational motion of Titan caused by the third harmonic of its gravitational potential
179 In [1], the mass of Titan, the largest moon of Sat urn, and parameters of the second and third harmon ics of its gravitational field were determined using the method of radio tracking ofExpand
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, theExpand
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 differentiatedExpand
New clues on the interior of Titan from its rotation state
Abstract The Saturnian satellite Titan is one of the main targets of the Cassini-Huygens mission, which revealed in particular Titan's shape, gravity field, and rotation state. The shape and gravityExpand
Titan's gravity field and interior structure after Cassini
Since its arrival at Saturn in 2004, Cassini performed nine flybys devoted to the determination of Titan's gravity field and its tidal variations. Here we present an updated gravity solution based onExpand
The Gravity Field and Interior Structure of Enceladus
The quadrupole gravity field of Enceladus and its hemispherical asymmetry is determined using Doppler data from three spacecraft flybys to indicate the presence of a negative mass anomaly in the south-polar region, largely compensated by a positive subsurface anomaly compatible with the existence of a regional subsurfaced sea at depths of 30 to 40 kilometers.

A partially differentiated interior for (1) Ceres deduced from its gravity field and shape
Gravity and shape measurements obtained from the Dawn spacecraft show that Ceres is a partially differentiated body, with a rocky core overlaid by a volatile-rich shell, as predicted in some studies, and show that the gravity signal is strongly suppressed compared to that predicted by the topographic variation.

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 stressExpand


Size and Shape of Saturn's Moon Titan
Titan’s lack of high relief implies that most—but not all—of the surface features observed with the Cassini imaging subsystem and synthetic aperture radar are uncorrelated with topography and elevation, and its depressed polar radii suggest that a constant geopotential hydrocarbon table could explain the confinement of the hydrocarbon lakes to high latitudes.

Doppler Measurements of the Quadrupole Moments of Titan
Abstract Measurements of the Doppler frequency change in a microwave beam sent to and transponded back from an interplanetary spacecraft are very sensitive to the quadrupole gravitational field of aExpand
Constraints on gas giant satellite formation from the interior states of partially differentiated satellites
An icy satellite whose interior is composed of a homogeneous ice/rock mixture must avoid melting during its entire history, including during its formation when it was heated by deposition ofExpand
We present values for the masses of Saturn and its major satellites, the zonal harmonics in the spherical harmonic expansion of Saturn's gravitational potential, and the orientation of the pole ofExpand
The Galilean satellites.
Modeling of landforms seen at resolutions up to 100 times as high as those of Voyager supports the suggestion that tidal heating has played an important role for Io and Europa. Expand
The long-term stability of a possible aqueous ammonium sulfate ocean inside Titan
We model the thermal evolution of a subsurface ocean of aqueous ammonium sulfate inside Titan using a parameterized convection scheme. The cooling and crystallization of such an ocean depends on itsExpand
