000004595 520__ $$aThe gravitational force exerted by  upiter on Io deforms the satellite and periodically changes its rotation. The gravitational interaction between Jupiter and Io in its precessing orbit also leads to the satellite having a small but finite obliquity. Both the tides and the rotation characteristics (librations and  obliquity) depend on the interior structure of Io. Here we evaluate the rotation for various models of the interior of Io, which take into account observational constraints from magnetic induction observations and astrometry. In particular, we assess the signature of a magma ocean on the librations and obliquity.
