On the librations and tides of large icy satellites.

Highlights: [•] We study the effects of elastic tidal deformation on the librations of icy satellites. [•] Libration amplitudes are calculated for the icy Galilean satellites and Titan. [•] Elastic effects on libration are on the order of a few percent for solid satellites. [•] Elastic deformation strongly reduces the potential amplifying effect of an ocean. [•] Length-of-day variations of Titan are substantially amplified by elastic effects. [Copyright &y& Elsevier]
