Recent work on theoretical modeling of nutation

In this note we make a brief sketch about the current state of the modeling of the Earth nutation, focusing on high frequency nutations. In particular, numerical nutations series are reported accounting for the harmonics (2,2), (3,1), (3,2) and (3,3) of the solid Earth potential, as well as for the case of the indirect effect due to the zonal harmonic of the second degree.
