Description:
The tables of nutation as given by Kinoshita & Souchay (1990) have
been constructed with use of the value of the general precession in
longitude as adopted by the IAU1976 (Lieske et al. 1977). The recent
observations agree to give a correction of about 0.3"/cy. to this last
value. Because of the interaction between the precession and the
nutation for a rigid Earth model, it became necessary to use an
updated value of pA, that is to say: pA=5028.7700"/cy and to
recalculate the largest coefficients of nutation influenced by this
change. This is one of the aim of this paper. Moreover, we study a new
contribution to the nutation not included in the preceding studies,
which are due to the periodic oscillations of the ecliptic. We also
calculate the planetary tilt-effect on the nutation pointed out by
Williams (1994), which was not included in Kinoshita & Souchay (1990).
At last all the coefficients of the nutation for a rigid-Earth model
have been recalculated, with an improved threshold of the potential
(5x10-10). We give final tables showing all the coefficients subject
to some change with respect to Kinoshita & Souchay (1990), for the
lunisolar part, including the indirect planetary effects. Only the
direct action of the planets on the nutation and the influence of the
J3 geopotential is not studied here. They will be the subject of a
next paper. At last a new value of the dynamical ellipticity of the
Earth is calculated in the following: HD=0.0032737548.
