Table 2

Size and density of the four internal layers of the Titan models consistent with the given constraints on mass and radius

Layer Thickness(km)/radius(km) Density (kg  m-3)

ice shell hsh =  {5} , {10,20,...,200}   {800,900,...,1200} 
ocean ho = 5−570  {1000,1100,...,1400} 
ice mantle Rm =  {2000,2025,...,2550}   {1200,1300,1400} 
ice/rock core Rc =  {1400,1410,...,2200}  2469−3176

Notes. The ocean thickness and the densities of the core are calculated for the given values of the other interior parameters. Within a given set denoted by curly brackets, the values are equally spaced.
