... In recent years, substantial information concerning the Io torus has been published. ... Explaining the observed steady state rotation of the torus seems to be difficult. The angular velocity of the torus must be in accordance with the celestial mechanics laws, of the same orders as Io's one. ... We wish to straighten out the situation describing the main geometric and kinematic features of the Io torus using a steady state model based on some of Alfven's ideas [Alfven, 1981]. ...
