| Abstract: | In a previous paper (The Rotation of Europa, Henrard, Celest. Mech. Dyn. Astr., 91, 131–149, 2005) we have developed a semi-analytical theory of Europa, one of the Galilean satellites of Jupiter. It is based
on a synthetic theory of the orbit of Europa and is developed in the framework of Hamiltonian formalism. It was assumed that
Europa is a rigid body and Jupiter a point mass. Several additional effects should be investigated in order to complete the
theory. The present contribution considers the effect of the shape of Jupiter and of the gravitational pull of Io. The sensitivity
of the main theory to a change in the values of the moments of inertia of Europa is also considered. |
