Recent developments in the theory of the Earth’s precession and nutation
Abstract
We report on recent advances in the theoretical modelling of the precession and nutation of the non-rigid Earth, with especial emphasis in those obtained by the authors following the Hamiltonian approach. We focus in second order components of the approximate solutions that come from various origins of physical and mathematical nature. They have been neglected in the available models up to now. Their contribution to the solutions, however, has a non-negligible magnitude, which in some cases reaches some tens of micro arcseconds.
