Effects on the nutation of the non-zonal harmonics of third degree Folgueira López, Marta Souchay, J. Kinoshita, Hiroshi In this paper, we calculate the coefficients of the nutation for a rigid Earth model due to the C-3m and S-3m (m not equal 0) harmonics of the geopotential, starting from the Hamiltonian theory as developped by Kinoshita (1977). We show that these coefficients are far from bring negligible as given the level of truncation of 0.1 mu as which is necessary in the reconstruction of the tables of nutation, and also that their value is very close to that given by Bretagnon st al. (1997). 2023-06-20T16:52:33Z 2023-06-20T16:52:33Z 2023-06-20T16:52:33Z 1998 journal article https://hdl.handle.net/20.500.14352/57296 0923-2958 10.1023/A:1008298122976 eng restricted access Kluwer Academic Publisher
