AB: Titan is composed of ice and silicates as the other icy satellites such as Europa and Ganymede. Its interior structure is presently not well known. More can be learned about the internal structure of Titan from the expected gravity potential and tidal love number measurements of the Cassini spacecraft. In this study we present the response of Titan to the tidal forcing by Saturn, as a function of the internal structure and rheology. In particular, we study the effect of a liquid layer beneath an ice I shell, the influence of ice I shell rheology and the possibly large effect of the viscosity of the high pressure ice layer between the ocean and the rocky core.
