Title: Dynamic reorientation of tidally locked bodies: application to Pluto
Abstract: Planets and moons reorient in space due to mass redistribution that is associated with various types of internal and external processes. While the equilibrium orientation of a tidally locked body is well understood, much less explored are the dynamics of the reorientation process (or true polar wander, TPW, used here for the motion of either the rotation or the tidal pole). The talk will cover the basic theory and observations, and our numerical solution to the problem will be outlined.
