| Abstract: | We perform a complete reconstruction of the series of the nutation for a rigid Earth model with the use of the very accurate
theories ELP2000 and VSOP82 for the motion of the Moon and the planets respectively, in such a way that all the individual
contributions up to 0.005 mas should be taken. This implies the introduction of the planetary effects, of the influence of
second-order parts of the potential of the Earth (J3, triaxiality), and some improvements due to an extension of the theory
at the second order. All this increase notably the number of coefficients to be taken in account, and modifies also in a significant
way the value of some of them. |
