Episodic volcanism on Enceladus: Application of the Ojakangas–Stevenson model

The main equations in the paper “Episodic volcanism of tidally heated satellites with application to Io” by Ojakangas and Stevenson [Icarus 66, 341–358] are presented; numerical integration of these equations confirms the results of Ojakangas and Stevenson [Icarus 66, 341–358] for Io. Application to Enceladus is considered. It is shown that Enceladus does not oscillate about the tidal equilibrium in this model by both new nonlinear stability analysis and numerical integration of the model equations.
