How tidal heating in Io drives the galilean orbital resonance locks (original) (raw)

NASA/ADS

Abstract

Tidal heating in Io is the most likely energy source of its volcanic activity. Tidal dissipation in Io and Jupiter also controls the resonance configuration among the three inner satellites. The formation of the several resonance locks is described in detail in this article. This model sets limits on the Q values of both Io and Jupiter.
