The Moon’s Physical Librations

Part II: Non-Rigid Moon and Direct Non-Gravitational Perturbations

Part of the NATO ASI Series book series (NSSB, volume 272)


Some relations between the non-rigidity of the Moon and its physical librations are described in this second part, including librations due to the tides and others due to the rotational motion. Starting from their nature, their cause and their behaviour, the different families of physical librations are presented here in a clear and compact classification.
